@Stephanie Lu modeled a cylindrical lens with random dimensions
- From Hyperion Optics:
- Optical glass substrates of optical filters mainly include absorption glass, such as JB510, CB535, HB850, colorless optical glass K9, float glass, B270, fused quartz, etc.
- Shanghai Optics Dichroic Filters Factory Standard substrate = UV Grade Fused Silica
- From http://www.bockoptronics.ca/bockoptronics/pdf/midopt/swir_filters.pdf
- SWIR Longpass Filters → Germanium substrate
- SWIR Bandpass Filters → Hard coated with BBAR
- https://www.schott.com/en-ca/products/optical-filter-glass-p1000266
- Dichroic SWIR bandpass filters have hard, all-dielectric coatings
- Many manufacturers will not provide their coating recipes
- Consider modeling with reflectivity or transmission curves
- Can be entered as a function of wavelength and angle, but the manufacturer is not likely to provide this information
- Could potentially ask the manufacturer for a black box model (according to some person on Reddit)
- Coatings in CODE V
