13 Caution: Overview Hot! This symbol warns the user that hot equipment may be present, and could create a risk of fire or burns. Caution: This symbol cautions the user that excessive humidity, if present, can damage certain equipment. Wear appropriate safety goggles to protect the eyes. Read this manual before using or servicing the instrument. 7

14 Risks of ultraviolet exposure Overview Caution: This instrument is used in conjunction with ultraviolet light. Exposure to these radiations, even reflected or diffused, can result in serious, and sometimes irreversible, eye and skin injuries. Overexposure to ultraviolet rays threatens human health by causing: Immediate painful sunburn Skin cancer Eye damage Immune-system suppression Premature aging Do not aim the UV light at anyone. Do not look directly into the light. Always wear protective goggles, full-face shield and skin protection clothing and gloves when using the light source. Light is subdivided into visible light, ranging from 400 nm (violet) to 700 nm (red); longer infrared, above red or > 700nm, also called heat; and shorter ultraviolet radiation (UVR), below violet or < 400nm. UVR is further subdivided into UV-A or near-uv ( nm), also called black (invisible) light; UV-B or mid-uv ( nm), which is more skin penetrating; and UV-C or far-uv (< 290 nm). Health effects of exposure to UV light are familiar to anyone who has had sunburn. However, the UV light level around some UV equipment greatly exceeds the level found in nature. Acute (short-term) effects include redness or ulceration of the skin. At high levels of exposure, these burns can be serious. For chronic exposures, there is also a cumulative risk of harm. This risk depends upon the amount of exposure during your lifetime. The long-term risks for large cumulative exposure include premature aging of the skin, wrinkles and, most seriously, skin cancer and cataract. Damage to vision is likely following exposure to high-intensity UV radiation. In adults, more than 99% of UV radiation is absorbed by the anterior structures of the eye. UVR can contribute to the development of age-related cataract, pterygium, photodermatitis, and cancer of the skin around the eye. It may also contribute to age-related macular degeneration. Like the skin, the covering of the eye or the cornea, is epithelial tissue. The danger to the eye is enhanced by the fact that light can enter from all angles around the eye and not only in the direction of vision. This is especially true while working in a dark environment, as the pupil is wide open. The lens can also be damaged, but because the cornea acts as a filter, the chances 8

15 Overview are reduced. This should not lessen the concern over lens damage however, because cataracts are the direct result of lens damage. Burns to the eyes are usually more painful and serious than a burn to the skin. Make sure your eye protection is appropriate for this work. NORMAL EYEGLASSES OR CONTACTS OFFER VERY LIMITED PROTECTION! Training Caution: UV exposures are not immediately felt. The user may not realize the hazard until it is too late and the damage is done. For the use of UV sources, new users must be trained by another member of the laboratory who, in the opinion of the member of staff in charge of the department, is sufficiently competent to give instruction on the correct procedure. Newly trained users should be overseen for some time by a competent person. 9

16 Additional safety precautions Introduction Overview The LSH Series Tungsten-Halogen and Globar lamps are light sources optimized for visible- (VIS) and near-infrared-region (NIR) spectroscopic applications. The Tungsten-Halogen light source is offered in 100 W and 250 W versions (LSH-T100, LSH-T250) and the Globar is available in a 70 W version (LSH-GC). The LPS-250 is a regulated DC power supply that drives the light sources, delivering up to 250 W at 24 V over 120 V AC line (mains) power. Consult the documentation provided with your LSH Series light source prior to operation for instructions on proper installation, operation, and maintenance. Always adhere to the following safety precautions when operating any of the LSH Series light sources and power supply: Visible radiation Caution: Your light source may emit high-intensity UV, visible, or infrared light. Exposure to these types of radiation, even reflected or diffused, can result in serious, and sometimes irreversible, eye and skin injuries. When using this light source, do not aim the light at anyone or look directly into the light or optical ports of the instrument. Any very bright visible light source will cause a human aversion response: we either blink or turn our head away. Although we may see a retinal afterimage (which can last for several minutes), the aversion response time (about 0.25 seconds) normally protects our vision. This aversion response should be trusted and obeyed. NEVER STARE AT ANY BRIGHT LIGHT-SOURCE FOR AN EXTENDED PERIOD. Overriding the aversion response by forcing yourself to look at a bright light-source may result in permanent injury to the retina. This type of injury can occur during a single prolonged exposure. Excessive exposure to visible light can result in skin and eye damage. Visible light sources that are not bright enough to cause retinal burns are not necessarily safe to view for an extended period. In fact, any sufficiently bright visible light source viewed for an extended period will eventually cause degradation of both night and color vision. Appropriate protective filters are needed for any light source that causes viewing discomfort when viewed for an extended period of time. For these reasons, prolonged viewing of bright light sources should be limited by the use of appropriate filters. The blue-light wavelengths ( nm) present a unique hazard to the retina by causing photochemical effects similar to those found in UV-radiation exposure. 10

17 Infrared radiation Infrared (or heat) radiation is defined as having a wavelength between 780 nm and 1 mm. Specific biological effectiveness bands have been defined by the CIE (Commission Internationale de l Eclairage or International Commission on Illumination) as follows: IR-A (near IR) ( nm) IR-B (mid IR) ( nm) IR-C (far IR) (3000 nm 1 mm) Overview The skin and eyes absorb infrared radiation (IR) as heat. Workers normally notice excessive exposure through heat sensation and pain. Infrared radiation in the IR-A that enters the human eye will reach (and can be focused upon) the sensitive cells of the retina. For high irradiance sources in the IR-A, the retina is the part of the eye that is at risk. For sources in the IR-B and IR-C, both the skin and the cornea may be at risk from flash burns. In addition, the heat deposited in the cornea may be conducted to the lens of the eye. This heating of the lens is believed to be the cause of so called glassblowers cataracts because the heat transfer may cause clouding of the lens. Retinal IR Hazards (780 to 1400 nm): possible retinal lesions from acute high irradiance exposures to small dimension sources. Lens IR Hazards (1400 to 1900 nm): possible cataract induction from chronic lower irradiance exposures. Corneal IR Hazards (1900 nm to 1 mm): possible flashburns from acute high irradiance exposures. Who is likely to be injured? The user and anyone exposed to the radiation or xenon lamp shards as a result of faulty procedures. Injuries may be slight to severe. General precautions Refer to the operation manual before attempting to replace the lamp. Only operate the light source when contained in the HORIBA Scientific LSH Lamp Housing. This housing will fully contain any parts of the lamp upon the event that the lamp envelope cracks. If the lamp envelope should crack, never touch it directly with your hands. Do not operate the light source beyond the total rated voltage. 11

18 Getting Started 2: Getting Started Unpacking Introduction The lamp housing was shipped in packing designed to protect it from harm under normal shipping conditions. If shipping damage is noticed upon delivery, the carrier should note such damage on the receipt, and sign all copies. This will ease processing a damage claim with the carrier. Note: Many public carriers will not recognize a claim for concealed damage if it is reported later than 15 days after delivery. In case of a claim, inspection by an agent of the carrier is required. For this reason, the original packing material should be retained as evidence of alleged mishandling or abuse. While HORIBA Instruments Incorporated assumes no responsibility for damage occurring during transit, the company will make every effort to aid and advise. Procedure 1 Open the top of the shipping carton and remove packing material until the Lamp Housing is exposed. 2 Reach down around the edges of the Lamp Housing, grasp the bottom, and lift it out of the remaining packing. 3 Place the Lamp Housing on a sturdy table. 4 Check through the packing thoroughly, and gather the small parts and documents that were shipped with the Lamp Housing. Inspection for damage Inspect the instrument for visible evidence of any damage. Check that all readily visible mechanical and electrical components are in their proper places and intact. If damage is evident, do not operate the instrument. Notify our Customer Service and the carrier at once. 12

19 Getting Started Caution: If for any reason the cover is removed, do not touch any of the optical surfaces in the instrument. Damage can easily occur and degrade performance. Such damage is not covered by the warranty. Fingerprints on a mirror or lamp surface may cause permanent damage. (See Care of Optical Components on p. 17) Attempts to remove a fingerprint usually do not significantly restore any lost performance, even though the cosmetic appearance may be improved. There is a high risk that attempts to clean will contribute to further damage and degradation of performance. 13

20 Installation Introduction Getting Started To attach the Lamp Housing to the monochromator, an adapter is required. Various adapters are provided, depending on to which spectrometer the Lamp Housing will be mounted. Some adapters are designed to accommodate a filter-wheel as well. Installation diagrams for each adapter are shown on the following pages. Environmental considerations Caution: Mount the light-source housing securely to your spectrometer. Improper installations will cause electrical arcing, overheating, and possibly shorten the life of the lamp. Do not turn the light source on until the housing is closed and mounted properly to the spectrometer to contain the light. Do not remove the housing cover when the light source is in use. Always turn off the electrical power before mounting the light source, replacing the lamp, or cleaning the housing. For best long-term performance, keep the Lamp Housing in a non-condensing atmosphere free of dust, corrosives and smoke. For best results, use the Lamp Housing in a room where temperature is maintained within ± 5 C. Caution: Do not block the air vents of the light source housing. Preventing the free flowing air can overheat and permanently damage the lamp. Do not use the light source in close proximity to paper, cloth or other combustible materials that can cause a fire hazard. Caution: Do not expose the light source to water or humidity. 14

21 Getting Started For TRIAX, FHR-series, and Gemini spectrometers 1 Referring to the appropriate figure on the next page, assemble the adapter starting by mounting the adapter flange to the spectrometer entrance-slit ring with the two 6-32 cap-head screws. For MicroHR and ihr-series spectrometers 1 Referring to the appropriate figure on the next page, assemble the adapter starting by mounting the adapter flange to the spectrometer entrance-slit ring with the two M3 cap-head screws. For M-II series spectrometers 1 Referring to the appropriate figure on the next page, assemble the adapter starting by mounting the adapter flange to the spectrometer entrance-slit ring with the two ¼ -20 screws. 15

22 Getting Started LSH-A270 installation, for direct mounting For all spectrometers 1 When the adapter (with filter-wheel, if so equipped) is assembled on the entrance slit, remove the top cover of the Lamp Housing. 2 Adjust the shoulder screws at the bottom of the adapter plate so that they fit snugly in the keyed slots at the bottom of the Lamp Housing s front plate. 3 With the Lamp Housing resting on the shoulder screws, insert the two 8-32 pan-head screws from the inside of the housing, to attach the housing to the adapter. 4 Install the bulb in the lamp mount at the front of the housing. Caution: Be careful not to touch the bulb envelope, because skin oils on the surface degrade performance and can cause premature failure of the lamp. 16

23 Getting Started 5 With the power supply switched off, connect the cable from the side of the lamp housing to the power supply. 6 Connect the banana plugs to the power supply. The red plug connects to the positive power output jack and the black plug connects to the negative power output jack. 7 Refer to the instructions shipped with your power supply. Based on the lamp specifications on page 8 of this manual, you may set the supply to power the lamp at any level up to its rated voltage. The lamp s spectral output is given for full power. If you choose to run the lamp at lower power, the spectral distribution will change. 8 Once the lamp is installed and powered, you may perform small adjustments to the coupling mirror mount at the rear of the housing. See the figure below for location of the adjusting screws. The mount has three contact points arranged so that there is a reference point at the corner (which should never require user adjustment) and x- and y-axis adjustments. Monitor signal strength after the exit of the monochromator to optimize the throughput. 17

24 Getting Started Assembling LSH + ACH-C + SampleMax + ihr320 1 Insert the two 6-32 caphead screws into the through holes in LSH-C and mount to two threaded holes on flat side of ACH-H. Typically these two parts are shipped premounted together as shown here: 2 Remove the slit-cover from ihr entrance-slit. 3 Using the M3 screws removed from the slitcover, mount the SampleMax ring (J350386) to the entrance slit of the ihr spectrometer. 4 Remove the SampleMax cover. 5 Place the four 8-32 mounting screws on the front interior wall of the SampleMax, and tighten them to attach to the SampleMax ring. 6 Place two pads under the back two feet of the SampleMax, and adjust the height to match the spectrometer s height. 18

25 Getting Started 7 Using two 6-32 screws, mount the M28 male adapter (J36540) to the ring on the back of the SampleMax. 8 Connect the ACH-C to the SampleMax via M28 adapters. 9 Remove the cover to the LSH housing. 10 Insert the lower large screws into the slots on the front plate. 11 Place the two Phillips-head screws on the inside of the LSH front plate, and mount to the LSH-C. 12 Attach the support screw and pad to the back underside of the LSH housing. 13 According to the instructions in this manual, adjust the mirror so that the light is centered on the exit, and the spot is centered on the sampleholder in the SampleMax. 19

26 Getting Started 14 Follow the instructions in the instrument manual for each component, to finish setting up the system. Completed system. 20

27 Assembling LSH + SampleMax + monochromator Getting Started Note: This procedure is for ihr320, ihr550, MicroHR, and others. 1 Remove slit-cover from the ihr entrance-slit. 2 Using the M3 screws removed from the slitcover, mount the SampleMax ring (J350386) to the entrance slit. 3 Remove the SampleMax cover. 4 Place the four 8-32 mounting screws on the front interior wall of the SampleMax, and tighten to attach to the SampleMax ring. 5 Place two pads under the back two feet of the SampleMax, and adjust the height so it matches the spectrometer s height. 6 Using two 6-32 screws, mount the LSH-A270 adapter to the ring on the back of the SampleMax (for absorbance/transmission measurements). The same mounting holes are used as for mounting on a monochromator s entrance slit. 7 Remove the cover to the LSH housing 8 Insert the lower large screws into the slots on the front plate. 21

28 9 Place the two Phillips-head screws on the inside of the LSH front plate, and mount to the LSH-A270. Getting Started SampleMax LSH Lamp Housing 10 (Optional) Attach the support screw and pad to the back underside of the LSH housing. 11 According to the instructions in this manual, adjust the mirror so that the light is centered on the exit, and the spot is centered on the sampleholder in the SampleMax. 22

29 Getting Started 12 Follow the instructions in the instrument manual for each component to finish setting up the system. Completed system. 23

30 3: Operation Precautions Operation Caution: Always wear UV-blocking goggles and UV skin-protective clothing and gloves. Do not stare into the light. Caution: Never touch the light source when it is on, or soon after it has been turned off, for it is hot and will cause serious burns. After turning the light source off, allow a minimum cooling time of 10 minutes before touching the housing. Caution: Only operate the light source when contained in the HORIBA Scientific LSH Lamp Housing. This housing will fully contain any parts of the lamp upon the event that the lamp envelope cracks. If the lamp envelope should crack, never touch it directly with your hands. Caution: When turning on any of the light sources which use the LPS-QTH, turn the voltage and current setting to zero (fine and coarse) before turning on the power to the LPS-QTH. Now turn up the current slowly, up to 25% of the specified voltage, and let it stabilize for a few minutes. Gradually increase the current by a small amount, letting the element stabilize every few minutes until you have reached 90% of the specified voltage (and power). Do not exceed this value, especially for the GB and GC units. Power (watts) = I 2 R, where current is I and resistance is R. 24

31 Orientation Operation The LSH-series Lamp Housing may be operated in any orientation. See the spectrometer manual for advice, if the proposed setup requires the spectrometer to be in an abnormal orientation. Image size versus slit-width When the Lamp Housing is connected to a monochromator, the slit-width you choose determines much about the output of the lamp + monochromator combination. The larger the slit-width, the wider the spectral bandpass is. See the spectrometer manual for more information about dispersion and bandpass. To calculate the bandpass for a given slit-width, Bandpass = linear dispersion slit-width The amount of light passed increases as the slit-width becomes wider, up to the point where the entire image of the source falls between the edges of the slit. See the specifications for image sizes. The practical minimum bandpass for a given monochromator is achieved when further reduction in slit-width does not result in decrease of the spectral bandwidth. Of course, smaller slits can be used to limit light, if that is desired. If the application demands a bandpass that cannot be obtained with the standard slits, please contact HORIBA Scientific to discuss options and alternatives, or to order additional fixed-slit inserts. 25

32 4: Maintenance Routine maintenance No routine maintenance is required. The moving parts are properly lubricated at the factory and will need no attention for many years of normal use. Except when changing lamps, you should not need to open the instrument after the initial unpacking. Maintenance Care of optical components Caution: Never touch the light source when it is on, or soon after it has been turned off, for it is hot and will cause serious burns. After turning the light source off, allow a minimum cooling time of 10 minutes before touching the housing. The mirrors and lamps in your Lamp Housing require no routine maintenance. Exercise care to prevent damage to their surfaces. Keep the Lamp Housing in an atmosphere free of dust, corrosives and smoke. Avoid touching an optical surface. Allow the lamp to cool normally before attempting to clean it. Blow off dust or other solid debris with dry dusting gas or nitrogen. Caution: Hold cans of dusting gas upright. If they are tilted or inverted, liquid propellant may be discharged, causing greater damage to the optics. If particles cannot be dislodged from the optical surface, consider leaving them alone, rather than risking surface damage. A fingerprint on a mirror or lamp surface should be flushed off as soon as practical by squirting the surface of the mirror with researchgrade methanol from a clean squeeze-bottle. Caution: Read the Materials Safety Data Sheet (MSDS) before using methanol. 26

33 Maintenance Caution: Keep the power off to avoid damage to the lamp or fan until all traces of methanol vapor have dissipated, eliminating risk of ignition. When flushing a mirror, place some paper towels below the mirror to absorb the excess methanol. Blow off the mirror with dry dusting gas or nitrogen to prevent spots or streaks. Be careful to avoid squirting or splashing other components. If the flow from the wash bottle does not remove the fingerprint, call Customer Service for further assistance. 27

34 Troubleshooting 5: Troubleshooting Introduction Your lamp housing is designed to provide years of reliable service. If you are experiencing a problem, review this section before contacting us to save time and help you to eliminate some simple errors that can be easily corrected. Common problems Some of the more common difficulties that may be encountered are listed below. With each, some suggestions are given that will correct the problem for most cases. Low signal-throughput Make sure that the light from the source is well-coupled to the entrance slit. Ideally, the light collected by the concave mirror should be imaged on the entrance slit. The coupling optics must be aligned on the optical axis of the monochromator. If in doubt about the axis alignment, position a low power HeNe laser at the exit of the spectrometer. Adjust the position of the laser to direct the beam backwards through the spectrometer. The beam will emerge from the entrance slit on the optical axis. It is then a simple matter to adjust the coupling mirror in the housing so that the beam strikes the center of the source lamp. If fiber-optics are directly coupled to the lamp, be sure that the fiber(s) are positioned at the focus. Align the fiber so that the cone of light converges centered on the axis of the fiber. Choose the type of fiber-optics to match the aperture of the housing. High stray-light level Enclose the complete optical path to prevent scattered light from entering the system. Check to be sure that all covers are snug and that light-seals at interfaces and covers are not damaged. In some cases, it may be possible to use the monochromator s slit-height limiter to prevent unused light from passing through the slit(s). Refer to the Service Policy in the following section to contact us for further assistance. 28
