UltraBlock UV Filter
Oct 2006
Deposition Sciences Inc. (DSI)Request Info
SANTA ROSA, Calif., Oct. 27, 2006 -- Thin-film optical coating manufacturer Deposition Sciences Inc. (DSI), introduces an advanced technology ultraviolet (UV) blocking filter, the UltraBlock.

The new UltraBlock filters are designed to block more than 99 percent of the harmful UV wavelengths between 200 nm and 380 nm and transmit greater than 90 percent (average) of the visible wavelengths between 425 nm and 700 nm.

Extremely stable over temperature and humidity changes, this robust, uniform coating meets or surpasses the severe abrasion, adhesion, humidity and salt fog tests of Mil-C-675 standards, according to the company.

DSI's UltraBlock product line can be applied to a wide range of transparent substrates (e.g. float glass, fused silica, sapphire and borosilicate glasses). The clear, UV-blocking filter coatings can also be applied to the highly curved surfaces of lenses, cover glasses and tubes. The company's proprietary MicroDyn reactive sputtering deposition technology is used to produce the high performance, highly durable UV blocking coating.

DSI's UltraBlock coatings can be used in LCD projectors, fiber illuminators, retail display lighting, museum lighting, food and beverage lighting and medical applications. UltraBlock is available from stock in flat sheets of Borofloat glass in thicknesses of 1.1 mm, 1.75 mm, 2.2 mm and 3.3 mm. Any thickness of the UltraBlock sheets can be readily fabricated into various parts, shapes and sizes to accommodate customers' specifications and applications, the company said.
