Features Wide-Acceptance-Angle Bandpass on Curved Surfaces
SANTA ROSA, Calif., July 12, 2006 -- Deposition Sciences Inc. (DSI), a maker of optical thin-film coatings, announces the availability of its new wide-acceptance-angle bandpass filter, what it said is an abrasive-resistant, superdurable filter that 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 the 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 company said.

The filter features coating consistency over the entire curved surface area. Developed with DSI's patented MicroDyn reactive sputtering technology, the filter is processed in the company's in-house facility using proprietary techniques to attain the necessary coating uniformity. According to DSI, this unique, difficult-to-achieve bandpass filter deposition across a curved lens is ideal for scanning, target designation, seeker heads and other applications requiring a uniform optical coating over curved surfaces.

GLOSSARY
bandpass
The range of frequencies that will pass through a filter or other device. Synonymous with passband.
bandpass filter
A filter with a transmission that is high for a particular band of frequencies, but that falls to low values above and below this band.
filter
1. With respect to radiation, a device used to attenuate particular wavelengths or frequencies while passing others with relatively no change. 2. See digital filter.
lens
A transparent optical component consisting of one or more pieces of optical glass with surfaces so curved (usually spherical) that they serve to converge or diverge the transmitted rays from an object, thus forming a real or virtual image of that object.
optical
Pertaining to optics and the phenomena of light.
sputtering
A vacuum deposition method in which the coating material (target) is removed from the surface of the coating source (cathode) by ion bombardment and deposited upon the substrates.
