Alternative Filters
Newport's Colored-Glass Alternative (CGA) Filters Newport's patent pending Colored-Glass Alternative (CGA) filters were developed to provide solutions for applications requiring long wave pass filters where the requirements of the application could not be achieved using colored-glass filters. Several product performance and construction attributes have been considered including RoHS compliance, chemical resistance, ultraviolet exposure resistance, autofluorescence, humidity resistance, temperature sensitivity, size & thickness limitations, and availability of cut-on wavelengths. From this list, RoHS compliance and cut-on wavelength availability were most often identified as limitations to be addressed. Our CGA filters were originally introduced in 28 as custom materials for OEM applications. The product line quickly gained acclaim from many market leading companies producing analytical instrumentation, and as we began to receive more and more requests for common cut-on wavelengths, it became clear that a standard product offering was needed in the marketplace. This catalog addresses that need, offering a group of thirty-four (34) standard cut-on wavelengths, available in four (4) standard sizes from inventory, in addition to our custom capability. Now, both researchers and OEM consumers can take advantage of this exciting solution, enjoying the rapid availability of standard products for lab and prototype applications as well as our continued custom capability of providing custom sizes of standard wavelengths and non-standard wavelengths as fullycustom solutions.

Introduction CGA filters are manufactured using our patented Stabilife coating technology which employs only RoHS fully-compliant materials. As such, these filters do not depend on the 4-year temporary exemption granted to allow manufacturers of colored-glass filters to continue to supply filters containing Lead and Cadmium compounds in their formulation. Full compliance to the RoHS directive provides assurance that these products will remain available for sale and will not add potentially harmful substances into our environment. These filters are manufactured by applying all-dielectric optical thin film coatings to fused silica or borosilicate glass substrates. The coatings are longwave pass interference filter coatings which have been designed to provide very wide spectral bands of reflection and transmission. The designs also provide a very steep transition from reflection to transmission making the filters a good choice for applications where wavelengths of interest are closely spaced with wavelengths that need to be eliminated. availability using an optical coating manufacturing process is virtually unlimited. This feature allows us to provide alternatives for currently available colored-glass filters, colored-glass filters that have been discontinued, and filters with cut-on wavelengths where no coloredglass filter is currently or was formerly available. GR-2883. CGA filters have been classified as having stain resistance of 1. (SR Class 1.) when tested per ISO 8424. Through careful selection of coating and substrate materials, and the use of reflection as the primary means of obtaining optical rejection, autofluorescence has been significantly reduced, particularly when compared to filters that rely primarily upon absorption to provide optical rejection. Our catalog offering of Colored-Glass Alternative filters is a series of fully-blocked, all-dielectric longwave pass filters at thirty-four (34) different cut-on wavelengths. The group of standard wavelengths was developed as a compilation of the cut-on wavelengths of longwave pass filter glasses currently offered by the major manufacturers of colored-glass filters, as well as some wavelengths that have been discontinued by these manufacturers. Four (4) different sizes are available at each wavelength: " diameter, 1" diameter, 2" square, and 6 " square. Standard CGA filters are supplied with a thickness of 1.1 mm. In addition to our standard CGA products, we routinely provide custom products based upon the basic product concept and designs. Custom capabilities are discussed in the section following the pages devoted to our catalog products. Chemical resistance, ultraviolet exposure resistance, autofluorescence, humidity resistance, and temperature sensitivity are all performance attributes that benefit from Stabilife optical coatings. Stabilife films exhibit very low sensitivity to thermal variation. They provide excellent resistance to damage due to handling, extreme nuclear and optical radiation, and severe environmental conditions. In the most severe applications, such as autoclave immersed nuclear reactor monitoring, Stabilife filters have demonstrated spectrally stable performance lifetimes exceeding 8, hours. Stabilife filters have been qualified for telecommunications applications per the requirements of Telcordia 2
Restrictions on Hazardous Substances (RoHS) The proliferation of electronics in virtually every part of the average person's life has brought many capabilities and conveniences that were unimaginable only a short time ago. However, as is often the case, along with the many benefits that these technological advances have conferred, some unintended negative consequences have resulted from this proliferation in the form of potential environmental harm from the disposal of waste electronics. In recognition of the present and potential risks to the health of our society as a result of the disposal of waste electronic equipment, the European Union (EU) has developed regulations to reduce the amount of potential pollutants used in manufactured products and to control the disposal of products that can not be manufactured without containing the certain targeted potential pollutants. The principal guiding regulations are the DIRECTIVE 22/95/EC OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 27 January 23 on the restriction of the use of certain hazardous substances in electrical and electronic equipment(rohs), and the DIRECTIVE 22/96/EC OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 27 January 23 on waste electrical and electronic equipment (WEEE). The RoHS regulation specifies that Member States of the European Union shall ensure that, from 1 July 26, new electrical and electronic equipment put on the market does not contain lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB) or polybrominated diphenyl ethers (PBDE). During the development of these regulations, the council recognized and made provisions for the fact that the complete elimination of these named materials could involve significant scientific development and therefore, established provisions for granting exemptions for a period of four years to allow sufficient time for the scientific development enabling the elimination of the hazardous substances to be completed. The relevance of these regulations to optical components lies in the fact that many electronics-based instruments employ optical technology as a key enabler. Just as all of the electronic components of these instruments are subject to the RoHS and WEEE regulations, so are all of the other components of the instrument including the optical elements. Many electronic-based instruments have employed colored-glass filters containing Lead and Cadmium compounds. Exemption status was established on 21 October 25 for Optical and Filter Glasses containing Lead and Cadmium for a period of four (4) years. The regulation requires that four years after an item is added to the list, a review is to be conducted with the aim of considering the removal of the component/s from the list of exempted materials. Unlike several Yellow, Orange, and Red Colored-Glass filters, Newport's Colored-Glass Alternative filters are fully compliant with RoHS regulations They do not rely on an exemption and therefore, are not subject to the uncertainty of the review process. Physical Properties Manufactured using Newport's patented Stabilife coating technology, our Colored-Glass Alternative (CGA) filters deliver exceptional durability in environments ranging from the most benign conditions found in a typical research laboratory to the most extreme conditions such as those found in nuclear reactors or desert battlefields. Abrasion Resistance, Adhesion, & Humidity Resistance CGA filters have been qualified for adhesion using the snap tape test specified in MIL-C-48497, for abrasion resistance using the eraser test specified in MIL-C-675, and for humidity resistance using the aggravated test specified in MIL-STD-81E. These tests are commonly used as benchmarks for determining the robustness of thin film coatings. Stain Resistance CGA filters have been evaluated for stain resistance using the Acid Resistance test set forth in ISO 8424. This test is used to determine the surface change that results from exposure to a strong acidic substance. The surface is exposed to a Nitric Acid solution (.5M/l) having a ph of.3 ±.5. Testing is conducted to determine the amount of time needed to etch into the surface to a depth of.1 mm. Newport's CGA filters have been confirmed to meet an SR1 rating which corresponds to greater than 1 hours of exposure. Since CGA filters are constructed of very thin layers of vacuum-deposited thin-film coating, an etch depth of.1 mm would likely result in a significant change in the spectral performance of the filter. No spectral change was evident after testing indicating an absence of any significant etching after the 1 hour exposure. Solubility The extreme hardness of the Stabilife coatings used to manufacture Colored-Glass Alternative filters allows these filters to be subjected to normal and severe weather conditions as well as to the repeated handling and cleaning that is commonplace for filters that are used in a lab environment, without sustaining any surface degradation. Unlike some Colored-Glass Filters that can suffer surface damage from prolonged exposure to rain or submersion in water, CGA filters maintain their clarity and spectral performance under such extreme conditions. 3
Optical Radiation Spectral Properties Stabilife coatings used to manufacture our CGA filters have been deployed in applications where they are exposed to intense ultraviolet and high energy visible radiation with no change in spectral performance after prolonged exposure. These filters have also been evaluated for Laser Damage Threshold using a frequency-doubled Nd:YAG laser operating at 532 nm with a pulse width of 1 ns and a repetition rate of 2 Hz. Typical damage threshold values exceed 1. J/cm 2. Extreme Temperature Colored-Glass Alternative filters are qualified for use at continuous operating temperatures between -1 C and +4 C. Newport's Colored-Glass Alternative filters are constructed using optical thin-film coating technology. Using Newport's patented Stabilife coating technology, many layers of refractory metal oxide film are deposited under vacuum in a precise sequence, defining the spectral signature of the filters. Unlike Colored-Glass filters which rely upon absorption to create the filter's spectral response, CGA filters utilize optical interference phenomena to create wide bands of veryhigh reflectance to create the blocking region of the filters, and wide bands of very-low reflectance to create the transmission bands of the filters. Using optical interference coatings to create longwave pass filters provides some distinct advantages over using absorptive coloredglass. Transition slopes between the rejection or blocking band and the transmission band can be made much steeper using interference coatings. On average, CGA filter slopes are 3 times steeper than the transition slopes of corresponding Colored-Glass filters. The spectral response of CGA filters are not dependent upon thickness of the filters. By contrast, the degree of rejection or blocking and the cuton wavelength of a filter constructed using colored-glass is directly dependent upon its thickness. The relationship between the thickness of the absorbing colored-glass is explained by the Bouguer-Lambert Law (also known as the Lambert Law) which defines the effect on the intensity of light transmitted through an absorbing substance in respect to its thickness. This feature allows Colored-Glass Alternative filters to be manufactured using very thin substrates while maintaining the required depth of blocking, enabling their use in a variety of applications where "small & thin" are desirable features. Filters manufactured using interference coatings also provide an advantage over colored-glass filters in their ability to provide any desired cut-on wavelength without incurring the time and expense of developing custom-formulated glass melts to achieve the desired cut-on wavelength. An equally important advantage of CGA filters is their formulation from 1% environmentally safe materials. This attribute stands in contrast to many colored-glass longwave pass filters that rely upon the use of Lead and Cadmium compounds to achieve their spectral signature. In addition to the above mentioned benefits of Colored-Glass Alternative filters over colored-glass filters, the cut-on wavelength of CGA filters can be tuned to slightly shorter wavelengths by positioning the filter at off-normal incidence to the source of illumination. This capability is a common phenomena associated with thin-film optical interference coatings. 4
Angle of Incidence Effects The cut-on wavelength of Newport s Corion Stabilife Colored-Glass Alternative filters will slightly shift lower in wavelength with an increase in the angle of incident collimated light. The amount of wavelength shift is dependent upon the incident angle and the effective index (n e) of the filter. This feature can be very useful in research applications by being able to custom tune a CGA filter to a specific desired wavelength. The following formula may be used to determine the wavelength shift of a filter in random polarized collimated light: Collimated Light = (n e2 sin 2 ) 1 2 (n e ) -1 where = Cut-on wavelength at angle of incidence = Cut-on wavelength at angle of incidence = Angle of incident light off normal incidence n e = Effective index of refraction; specified as a numerical value derived from the indices of the thin film layers of the CGA filter = Angle of Incidence Filter Examples of Angle of Incidence Effects on Selected CGA Filters CGA-345 CGA-345_AOI AOI 1 9 8 7 % Transmittance 6 5 4 3 2 1 2 225 25 275 3 325 35 375 4 425 475 5 525 525 55 575 6 Black = º incidence (Random POL) Blue = 1º incidence (Random POL) Red = 2º incidence (Random POL) Typical angle of incidence effects for CGA-345 filters with effective index of refraction (n e ) of 2.147 Incident Radiation Collimated @ Normal Incidence Collimated @ 1 off-normal (Random POL) Collimated @ 1 off-normal (P-POL) Collimated @ 1 off-normal (S-POL) Collimated @ 2 off-normal (Random POL) Collimated @ 2 off-normal (P-POL) Collimated @ 2 off-normal (S-POL) Effective Cut-on λ at 5% Transmittance 345. nm 343.9 nm 343.4 nm 344.2 nm 34.3 nm 338.8 nm 341.8 nm 5

Cone-Angle Effects In the preceding examples, the wavelength changes were modeled under the assumption that the incident light was collimated. In some applications, the incident light is presented at the filter in a convergent or divergent cone. The cone is made up of many light rays at various angles ranging from normal incidence to the extreme angle defining the full cone. The effect of this collection of rays is a weighted average of incident light, producing a wavelength shift toward shorter wavelengths that is smaller than the shift that would be produced if collimated light was presented to the filter at the extreme angle of the full cone. Filter Examples of Cone-Angle Effects on Specific CGA Filters The tables that follow illustrate the theoretical blue-shift that would result in the cut-on wavelength of various Colored-Glass Alternative filters when illuminated with incident radiation in a 1 full-cone and a 2 full-cone.

Stabilife Coating Technology Film Density & Spectral Stability Newport's Colored-Glass Alternative filters are manufactured using our patented Stabilife coating technology. Some of the key features and benefits of this technology are provided in the paragraphs that follow. Film density is a critical factor affecting the spectral stability of an optical coating. Un-stabilized metal oxide thin film coatings typically exhibit a significantly lower packing density than Stabilife coatings. This occurs as a result of the intrinsic growth properties of the coating materials when deposited using methods which do not enhance film densification. The film structure of un-stabilized metal oxide film tends to be columnar with a significant number of voids. The presence of these voids contributes to the occurence of environmentally induced spectral shift in un-stabilized external coatings. Changes in wavelength, which are influenced by the presence of voids, tend to be elastic in nature and depend upon the ambient relative humidity in which the coating is being used. The permeability of the film will determine the degree to which this phenomenon will occur. Spectral shifts in the range of 2-5% of wavelength are typical of un-stabilized metal oxide coatings. Stabilife coatings have a higher packing density and lower void ratio than unstabilized metal oxide coatings and are therefore less affected by water absorption. They typically exhibit total wet-to-dry shifts of less than.2% of wavelength. Humidity Stability of Stabilife Filters Newport's Stabilife Reactive Ion Plating Deposition System 1 Stabilife optical filters and coatings are manufactured using two patented processes for the deposition of metal oxide thin film optical coatings; Reactive Ion Plating (RIP) and Hybrid Plasma Enhanced Deposition (HPED). Both processes yield highly dense, thin film coatings with extraordinary hardness, abrasion resistance, and adhesion to the substrate. Our Stabilife processes have been in fullscale production at our Corion coating facility in Franklin, Massachusetts since the early 199's. Transimission 8 6 4 2 Spectral Stability Optical components which directly affect the spectral performance of an optical system must be able to deliver repeatable and accurate wavelength vs transmission response, regardless of the operating conditions. In some applications, un-stabilized metal oxide optical coatings or laminated soft-film coatings are adequate to meet the required performance parameters. However, for some of the more demanding applications such as fluorescence detection, wavelength stability is absolutely critical to insure dependable results. Stabilife optical filters and coatings provide the solution for these high accuracy applications. 16 162 164 166 167 Measured transmittance scans of a Stabilife filter at % and 1% relative humidity. Scans are exactly overlaid as no shift is discernable at the standard scan speed for a 3nm bandwidth filter. 79
Thermal Properties & Spectral Stability Physical Durability Stabilife films are typically 5 to 1 times less sensitive to thermal variation than un-stabilized metal oxide films as a result of film densification. Temperature change functions as a catalyst for moisture migration in thin films having a significant volume of voids. When un-stabilized films are exposed to high temperatures, moisture migrates out of film voids contributing to the wavelength change discussed earlier. The high film density and reduced permeability resulting from the Stabilife processes reduces this effect providing the maximum spectral stability available for all types of precision coatings including bandpass, dichroic, edge, notch and polarizer coatings. 1% 9% 8% 7% 6% 5% 4% 3% 2% 1% % -6 C Un-stabilized 3 C 535 537 539 125 C Stabilife thin-film optical coatings have demonstrated excellent resistance to damage due to handling, extreme nuclear and optical radiation, and severe environmental conditions. In the most severe applications, such as autoclave immersed nuclear reactor monitoring, Stabilife filters have demonstrated spectrally stable performance lifetimes exceeding 8, hours. Stabilife filters have been qualified for telecommunications applications per the requirements of Telcordia GR-2883. While most applications are much less demanding than these, the same robust coatings as are required for extreme applications are routinely supplied for all Stabilife products. In the course of normal production, Stabilife films are tested for adhesion using the snap tape test specified in MIL-C- 48497, for abrasion resistance using the eraser test specified in MIL- C-675, and for humidity resistance using the aggravated test specified in MIL-STD-81E. Stabilife thin-film optical coatings require no additional protection such as hermetic sealing using lamination or other processes, to achieve their exceptional durability.
