Deposition Sciences (DSI), a producer of highly durable thin film coatings, announces what it calls a revolutionary wide acceptance angle optical band pass filter
This abrasive-resistant, super-durable filter can be coated onto curved surface lenses for high accuracy applications.
The thin film coating blocks wavelengths from the visible region of the spectrum (400nm) into the shortwave infrared wavelength (1200nm) with a high transmission at 1064nm.
It allows uniform optical performance of the coating on the center area of a lens at normal incidence and performance on the edge of a lens at high angles of incidence.
Designed for use across a large cone angle, DSI's advanced optical interference filter is engineered for demanding tasks in which the film needs to have a high transmission over the entire surface of a curved lens.
The new wide acceptance angle band pass filter features unparalleled coating consistency over the entire curved surface area.
Developed with DSI's patented MicroDyn reactive sputtering technology, the filter is processed in its in-house facility using proprietary techniques to attain the necessary coating uniformity with exceptional results.
This unique, difficult-to-achieve band pass filter deposition across a curved lens is ideal for scanning, target designation, seeker heads and other applications requiring a uniform optical coating over curved surfaces.
DSI's coating capability ranges from the ultraviolet (UV), through the visible and includes near-infrared (NIR), midwave-infrared (MWIR) and out to the longwave-IR (LWIR).
At the heart of these capabilities is DSI's patented MicroDyn reactive sputtering technology enabling superior multilayer thin film coatings for optics, Mems and other thin film technologies.
