Since you're working inside of SOLIDWORKS, you can import a wide range of components from manufacturers to help layout your optical bench.
You can then assign optical material properties to mirrors, beam splitters, lenses and other components. Optical material properties can be selected from Photopia’s library or you can create custom materials using our open library format. Any values of directional reflection & transmission, lens extinction coefficients, AR coatings and indices of refraction can be set over any wavelength range. Photopia can also model material scattering with measured or theoretical BSDF data.
