  • Optical Band Pass Filter

Deposition Sciences Inc. (DSI)Request Info
SANTA ROSA, Calif., July 14, 2006 -- Deposition Sciences Inc. (DSI), producers of highly durable thin-film coatings, has introduced a wide-acceptance angle band pass filter. This abrasive-resistant, super-durable filter can be coated onto curved surface lenses for high-accuracy applications.

DepositionSciencesBandPassF.jpgThe thin-film coating blocks wavelengths from the visible region of the spectrum (400 nm) into the shortwave infrared wavelength (1200 nm) with a high transmission at 1064 nm. It allows uniform optical performance of a coating on the center area of a lens at normal incidence and performance on the edge of a lens at high angles of incidence.

Designed for use across a large cone angle, DSI's advanced optical interference filter is engineered for demanding tasks in which the film needs to have a high transmission over the entire surface of a curved lens.

The new wide-acceptance angle band pass filter features unparalleled coating consistency over the entire curved surface area. Developed with DSI's patented MicroDyn reactive sputtering technology, it is suitable for scanning, target designation, seeker heads and other applications requiring a uniform optical coating over curved surfaces.
