SANTA ROSA, Calif., Sept. 25, 2006 -- Deposition Sciences Inc. (DSI), manufacturer of highly durable thin-film optical coatings, announces what it said is an innovation in high temperature and high density performance in its HeatBuster cold mirror product line.

This new cold mirror coating technology withstands light levels above 200 W per square centimeter and extreme temperatures above 400 °C. These cold mirrors feature reflectivity values of up to 98 percent across the visible spectrum and extremely low reflectivity in the infrared, with transmission of equal to or less than 20 percent in the 800-nm to 2500-nm waveband.

HeatbusterColdMirror.jpgDSI's HeatBuster cold mirrors can be designed to operate over a wide range of angles. They can be applied to both infrared transparent substrates (e.g. glass, fused silica and sapphire) and opaque materials (e.g. stainless steel and electroformed nickel). DSI's cold mirror coatings efficiently reflect visible light without changing the color appearance of the source. The coatings can also be applied to the highly curved surfaces of parabolic and elliptical reflectors, meeting or surpassing strict adhesion standards.

The new "white light" coatings are ideal for use in fold mirror and light tunnel applications where a focused light beam is needed to reduce the size of the optics and the overall unit, the company said. With their high reflectivity at high angles of incidence, these all-dielectric cold mirrors can be used to replace silver coated mirrors in light tunnel applications.

DSI's proprietary MicroDyn sputtering technology yields a high performance, highly durable cold mirror coating. This coating is extremely stable over temperature and humidity changes, meeting the severe abrasion, adhesion, humidity and salt fog tests of Mil-C-675 standards. HeatBuster cold mirrors are suitable for applications in projection display, medical, high power illumination and digital cinema projection, DSI said.
