Optical Material Library
The Optical material library is included with the Ray Optics Module and the Wave Optics Module. It contains more than 1700 materials, including more than 500 optical glasses from the following optical glass manufacturers:
•
CDGM Glass Co., Ltd
•
Corning Incorporated
•
Ohara Inc.
•
Schott AG
For most of these glasses, the refractive index is defined using optical dispersion coefficients to support accurate ray tracing of polychromatic light. Many of these glasses also include tabulated internal transmittance data as a function of wavelength, enabling volumetric light absorption to be predicted, as well as coefficients that describe the temperature dependence of the refractive index. Finally, most optical glasses include additional properties such as density, Young’s modulus, Poisson’s ratio, thermal conductivity, specific heat capacity, and thermal expansion coefficient, which facilitate coupled structural-thermal-optical performance (STOP) analysis.
For other organic, inorganic, and miscellaneous materials, the properties are based on data from
Ref. 1
. Here, the material properties are frequency-dependent values for the real and imaginary part of the refractive index.
