Optical filter coatings deposited on tubes
Special tooling and processes permit coating the outside of tubes with durable and precision optical filters that withstand extreme heat, temperature fluctuations and high humidity.
Coating complex glass/ceramic/metal shapes
A low pressure chemical vapor deposition can coat complex shapes in almost all types of optical glass, including ball lenses, crystalline materials, ceramics and metals.
This precision deposition technology permits DSI to apply multiple coatings on a single substrate with dimensions as small as 100 microns, with accuracy of plus or minus one micron (+ / -1 um) with feature placement accuracy of + / - 5 microns.
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 infrared.
They can be applied to a variety of substrates in many shapes and sizes, as well as wafer substrates up to 100 mm 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 MicroDynandacirc; 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.
