filters are optical elements that are designed to transmit
a specific spectral band with high efficiency, while reject
others. The characteristics of the bandpass are controlled
by multilayer dielectric coatings
commercial quality window or precision window. Please refer
to the optical
Long wave pass (LWP) filter coating
T<1%@200-570nm & T>90%@630-1100nm, AOI=0deg.
Short wave pass (SWP) filter coating
Tavg<1%@750-1100nm & Tavg>90%@400-680nm, AOI=0deg.
