Patterned filters cover
wide range of wavelengths
Deposition Sciences has announced an innovation in dichroic filters coating-deposition capabilities
The new Patterned Dichroic Filters are created in-house using the latest photolithography equipment and DSI's advanced coating techniques. This precision deposition technology permits DSI to apply multiple coatings on a single substrate with dimensions as small as 100um, with accuracy of +/-1um with feature placement accuracy of +/-5um.

DSI's Patterned Filters can be designed to operate over a wide range of wavelengths and offer superior performance from the near ultraviolet to the infra-red.
They can be applied to a variety of substrates in many shapes and sises, as well as wafer substrates up to 100mm diameter in materials such as silicon, glass, sapphire and fused silica.
The new Patterned Dichroic Filters from DSI will meet or surpass strict adhesion and durability standards maintaining stability even in extreme temperatures and adverse conditions.
Patterned Filter coatings are ideal for use in CCD imaging applications where a single optic is required to perform multiple functions.
DSI's new coatings feature precise patterning and superior reliability, making them suitable for use in satellite, aircraft and other tasks that require durable, patterned filters for optoelectronic and optomechanical devices.
DSI's proprietary MicroDyn sputtering technology, utilised in creating Patterned Dichroic Filters, yields high performance, highly durable coatings.
This highly durable, uniform coating is extremely stable over temperature and humidity changes, meeting the severe abrasion, adhesion, humidity, and salt fog tests of MIL-C-675 standards.
