Optical filters for light sources

To use one or more optical filters is often the simplest way to isolate a small region of the light source spectrum, to remove unwanted spectral bands, or to attenuate the light beam. We offer a wide selection of narrow and broadband filters, neutral density filters and special filters to reject unwanted radiation or heat from a system or to protect filters and other optics.
