Broadband Non-Polarizing Cube Beamsplitters (BNPB)

-
- Hybrid – non-polarizing
- < 10% absorption in the Hybrid coating
The hybrid coating is a Metal & dielectric film combination which is spectrally uniform over the indicated wavelength range. It is also insensitive to polarization . R/T ration of 30/60 or 45/45 maybe chosen.
