Transparent coatings resist temperature changes
Deposition Sciences' coatings yield high-performance, highly uniform, transparent conductive filters that remain extremely stable while withstanding high thermal loads and changes in humidity.
The thin film coating blocks wavelengths from the visible region of the spectrum (400nm) into the short-wave infra-red wavelength (1200nm) with a high transmission at 1064nm.
It allows uniform optical performance of the coating on the centre 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 bandpass 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 their in-house facility using proprietary techniques to attain the necessary coating uniformity with exceptional results.
This unique, difficult-to-achieve bandpass 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.
