Heraeus offers a variety of information on several websites. The optical properties of bulk substances is often quoted as "n" and "k" values, which are the real and imaginary parts of refractivity, respectively. All raw filter data used for this calculation program were supplied to us by the SCHOTT AG with kind permission to be used in our online calculator. here The origin of the curve must be identifiable by a direct link to our online calculator. The transmittance of CaF 2 crystals is >99% at B 6, 4370-4379 (1972) Data [CSV - comma separated] [TXT - tab separated] [Full database record] Optical transmission calculator If, for example, maximum transmission of 10% is reached within the measuring range, the Y-axis, which is the transmittance, is scaled to a value range of 0-10% to allow a more accurate analysis of the transmission in wavelength ranges with lower transmissions. Please consider that it is not recommended to choose filter thicknesses below 1mm because compliance with the material's transmission specifications at lower thicknesses isn't safe anymore. We reserve the right to change any technical and non-technical data without notice. The utilization of the data in this filter curve calculation program takes place with the kind permission of the SCHOTT AG. Using our calculator, you can compute individual filter transmission curves. The use of this optical glass filter calculator takes place entirely and solely in any implication at your own risk. This calculator program is protected by national and international copyright laws and might not be copied or commercially exploited without our written permission. The UV transmission is important for microlithography applications. "k" relates to optical absorption, and this calc determines the transmission of a sample. All measurement data used for the calculation of the filter curves are the property of the SCHOTT AG. Here you can convert optical density to transmittance and vice versa. Optoplex Corporation is a leading supplier of cutting-edge photonic components, modules and subsystems for dynamic wavelength management and signal conditioning. Optical glasses with excellent homogeneity and transmittance at 365nm are for example FK5 HT, LLF1 HT and LF5 HHT with transmittance >99% at 10mm thickness . Many demanding applications or those in … The internal transmission is essential to know for the design of cemented filter combinations. %T is 100 times this result, and %Absorption is 100-%T. . The company designs, develops, manufactures, and markets high performance fiber-optic products to communications networks, and provides customized solutions to instrument, defense, spectroscopy and sensing … Our free online SCHOTT-filter calculator for calculating the transmission of all available optical glass filters made of SCHOTT color glass filter material and neutral density filters is online and at your disposal with immediate effect. With a click on the button "Calculate transmission curve" It is a helpful tool to calculate the transmittance or optical density of a neutral density filter. You can change your preferences in the, HVAC (Heating, Ventilating, and Air Conditioning). We don't take over any guarantee or liability for any technical data, specifications, or result. No specification. Additional information on the performance of the various grades in different environments can be found Using our calculator, you can compute individual filter transmission curves. Rev. (Internal transmittance, surface reflection-losses NOT included). Fused silica exhibits an excellent transmittance (98%) down to 193nm . If you like this tool, we invite you to place a direct link to this calculator on your website. Beyond this level all values must be extrapolated. Online transmission calculator for SCHOTT optical color glass filters Our online SCHOTT-filter calculator allows you to individually calculate and analyze the transmission curves of nearly all SCHOTT color glass filter materials, which makes it easy to find out the best optical color glass filter … you accept our terms & conditions for the use of our SCHOTT-filter calculator below. We provide this useful tool to you for free. Optical constants of the noble metals, Phys.

Our free online SCHOTT-filter calculator for calculating the transmission of all available optical glass filters made of SCHOTT color glass filter material and neutral density filters is online and at your disposal with immediate effect. Choose this option to see the internal transmission of the filter. Absorbance is measured with a spectrophotometer, which establishes the light transmission and calculates the absorbance. Transmission Calculator In the visual spectrum fused silica transmits light more efficiently than other optical glasses. © 1994 - 2020 Präzisions Glas & Optik GmbH. In order to help you select the most suitable fused silica grade, we offer the tool below. It will show you the transmission or attenuation characteristic of the different Heraeus material grades. Please solely use this link to refer to our calculator, and please consider our terms & conditions for using our optical glass filter calculator directly below. The optical transmissionof a sample is given by 10 to the powerof -(optical density). An optical densityof 1 corresponds to 10% transmission, and of 2 to 1% transmission. Note: We do not take over any responsibility or guarantee for any result! This option does NOT consider the surface reflection losses which under normal conditions occur.
