1. Beamsplitter Side 1 features 10 to 18 thin-film dielectric layers vacuum-deposited on the substrate.
2. Optional: Side 2 can be coated with a multilayer Anti-Reflection (AR) coating to reduce surface reflection from ~4% down to below 0.5%, minimizing ghost images and stray light.
3. Coating process: PVD-EBGE (Physical Vapor Deposition - Electron Beam Gun Evaporation).
4. The spectral transmittance curves shown are measured at a 45° angle of incidence (AOI = 45°).
5. Spectral curves represent actual sample measurements and may vary slightly from manufacturing lot to lot, while remaining within defined optical specifications.
