Dichroic filter glass surplus
WebAndover is a leader in flat response neutral density filters in the UV to near-infrared (250nm-2000nm) and far-infrared (2000-14000nm). These coatings are hard and pinhole-free. Our ND Filters exhibit industry-leading spectral neutrality over a broad wavelength range, with optical densities up to 4.0. WebDichroic beamsplitters are more expensive than absorption based filters (dyes trapped in glass) but more rugged because most of the incident radiation is either reflected or transmitted and cannot damage the optic. The performance of dichroic beamsplitters is caused by interference. Alternating layers of optical coatings on glass substrates produce
