Long pass filters block a select band of shorter wavelengths. This example, long wave pass cutoff filter provides average reflectance more than 99% from 400-700nm, 50% cutoff point at 750nm ±10nm and 95% transmission from 780-1200nm. Custom long wave pass filters are available on request.

Short pass filters block a select band of longer wavelengths. This example, short pass filters block a select band of longer wavelengths. short wave pass cutoff filter passes light from 325-450nm and blocks visible light from 500-700nm. It has a 50% point at 470nm ±10nm. Custom short wave pass filters are available on request.
