Longwave Pass Filters (VIS)

Longwave Pass Filters (VIS)

Longwave pass filters (VIS) are designed to transmit wavelengths longer than 5% of the "cut-on" values and block the shorter wavelengths. The longwave pass filters (VIS) are optimized for zero degree angle of incidence. The inband transmission is typically above 75% and the average out-of-band blocking is less than 0.1%.

Custom sizes and wavelengths are available upon request.
