UltraBlock filters are designed to block over 99% of the harmful ultraviolet wavelengths between 200nm and 380nm and transmit over 90% (average) of the visible wavelengths between 425nm and 700nm
Deposition Sciences (DSI), manufacturer of highly durable thin film optical coatings, introduces an advanced technology ultraviolet (UV) blocking filter, the UltraBlock.
UltraBlock coatings efficiently transmit visible light without changing the color appearance of the source material.
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.
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 are ideal for use 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 1.1mm, 1.75mm, 2.2mm and 3.3mm.
Any thickness of the UltraBlock sheets can be readily fabricated into various parts, shapes and sizes to accommodate customers' specifications and applications.
