BP850 narrow-band filter

Narrow band interference filter is a kind of narrow bandwidth, allowing specific wavelengths of light through the optical devices, so the short wavelength band cut-off or reflection.

Pass filter with multiple epidural with my company by ion assisted deposition of nano materials of high vacuum evaporation a layer, good compactness, high image resolution.
