Optical Bandpass Filter

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.
The
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.
