2 Diode Laser System Accessories & Options Optical Options for Laser Diode Systems Option # A Z Focusing Lenses Description The "A" option is a fixed aperture stop placed on the end of the laser system. This aperture stop effectively blocks parts of the laser beam so that the projected spot is circular. This also results in a reduction in the system's optical output power. The "Z" option is an external lens assembly that incorporates the optics to correct for the laser diode's astigmatism. Refer to page iv and page 6 for descriptions of this condition and correcting method.

The laser diode used to make the individual laser line measurements was a 635nm laser with a beam divergence of 8x31mm. Note: The Line Generating Lenses will increase the length of the system by the following amount: L1-9mm ±0.5 L2-L13-7mm ±0.5 L12 and L13 are low cost units. Note: The line generated will not be a straight line. The degree by which the line will deviate is dependent upon the length of the projected line. The equation for determining this deviation is, 0.3mm + (0.002 x laser line length). Fiber Optic Pigtail Assemblies The fiber optic pigtail assemblies include several elements. An adapter is permanently attached to the system case. Depending upon the assembly ordered, a length of either multimode, single mode, or polarization maintaining fiber will be provided along with the appropriate connectors. All fiber has 125µm cladding and 3mm jacket. Contact the factory for all fiber optic pigtail assembly pricing. Price is dependant on wavelength, fiber length, and connectors.

3 Power Technology Incorporated (501) Mechanical Options for Laser Diode Systems Option # Description C The "C" option incorporates a fixture within the system to move the diode in relation to the lens so as to center the beam axially with the laser system housing. Adding this option results in four recessed set screws being added to the exterior of the system case (see diagram). K The "K" option is a Kapton tape wrap used to electrically isolate the laser system case when mounting. While most laser systems are case isolated, this option can be used for those that are not. Electrical/Control Options for Laser Diode Systems Option # Description B The "B" option is a 9V (PP9) battery clip supplied "installed". Dx The set of "D" options enable the operator to have digital control over the system. The digital potentiometers can be used in a transparent mode or to store the setting even when the power is removed. Depending on the system compatibility, there are three types of digital control. E The "E" option is an external fan switch. X The "X" options represent a whole range of electronic control adjustments. These are categorized by Constant Power Control, Constant Current Control, Temperature Range Control, and Frequency Selection of Modulation Control. Frequency Selection of Modulation Option Option X34 External User Programmable Crystal Trigger The Option X34, when added to any of the internal crystal modulated laser diode OEM systems, allows the user to externally step the divider and change the modulation to a frequency within the capability of the crystal oscillator. All frequencies generated are derived from a single built-in quartz crystal oscillator and exhibit the same high levels of accuracy and stability as those of the base frequency supplied by the crystal. The Option X34 is a low power, TTL compatible option that includes a control connector. The "C" option is compatible with these systems: PM, PMB, PMD, PMT, PMX, PPM, PPMT, PPMX SPM, SPMT, SPMX This wrap will slightly increase the diameter of the system case. It will also prevent effective heat dissipation. The "B" option is only compatible with the CPM. Refer to each system's specifications for compatibility. The option designation for each type is: D1 - Optical Output Power Digital Control D2 - Laser Drive Current Digital Control D3 - Laser Temperature Digital Control The "E" option is compatible on systems with fans.

5 Handling and Safety Safety Precautions These Laser Diode Systems are visible and infrared laser sources. The energy emitted may be invisible to the human eye. These systems emit radiation anywhere in the 630 to 2100 nm wavelength range, depending on the model ordered. Use CAUTION to avoid hazardous exposure from the laser system beam. Never look directly into the beam from the laser system under any conditions, and take precautions to eliminate exposure to a direct or reflected laser beam. Make sure to turn on laser systems in a safe and controlled area. All of the laser systems, which Power Technology manufacturers, emit sufficient optical power to constitute a possible hazard to the human eye. Handling/Operation Precautions Power Technology Incorporated Laser Diode Systems are very reliable under normal operating conditions. However, if not properly handled or operated the diode can easily be damaged or destroyed. The following precautions should be taken to ensure that the laser is protected. 1. Do not adjust the focus, on systems that operate in Constant Optical Output Power Mode, while operating at full power. The photodiode feedback circuit relies on the reflections off the lens to monitor the laser power. Adjusting the focus changes these reflections which could result in laser burnout. 2. Do not operate equipment near the laser diode which may generate high frequency electrical surges. The laser diode leads can pick up electrical surges which may destroy the diode in the induced electric field. 3. Avoid touching the laser system lens. Contamination and scratches on the lens may result in decreased optical output power and distorted far-field patterns. If the lens becomes contaminated, clean using a cotton swab with ethanol. LASER RADIATION AVOID DIRECT EYE EXPOSURE PEAK POWER <5MW WAVELENGTH CLASS IIIA LASER PRODUCT LASER RADIATION AVOID DIRECT EXPOSURE TO BEAM PEAK POWER <500MW WAVELENGTH CLASS IIIB LASER PRODUCT Most of the systems in this catalog are designated solely as OEM components for incorporation into the customer's end products. Therefore, they do not comply with the appropriate requirements of FDA 21 CFR, Section and for complete laser products. The complete laser product manufacturer is responsible for complying with these requirements (see above for the appropriate warning labels). Power Technology Inc. will supply labeled systems or, upon written request, loose labels for use by the customer. Retaining this safety label does not guarantee the final product will fully comply with FDA requirements. These systems have been registered but not certified as per FDA 21 CFR, Section (a)(3)(i). For further information call CDRH (301) The CPM and RS systems are certified as a complete laser products. However, this certification is void if the unit is enclosed or otherwise inaccessible, or if the labels are modified or removed. Refer to the RS specifications for more details on certification of this system.
