These coatings reduce the reflection from the surface of an optic. They are used to increase the throughput of the optical system and to reduce ‘ghosting’ and parasitic back reflections in an optical system.
DSI’s proprietary Low Pressure Chemical Vapor Deposition (LPCVD) technology now makes it possible to deposit high performance, highly durable AR coatings on complexly shaped objects. Our LPCVD process provides a highly uniform AR coating over the entire surface of your complexly shaped optic in one operation.
DSI is leader in providing the aerospace and defense industry with critical infrared, multi-spectral, and visible domes. Our LPCVD process provides a highly uniform AR coating over the entire surface of your dome in one operation.
These lenses are typically used to collimate (in one dimension) the light emitted from a laser diode. Typical fiber sizes range from Ø0.08mm to Ø1.0mm and larger. DSI’s proprietary coating process will uniformly coat Fiber Rods for any VIS or NIR wavelength that you require.
Laser Windows are used to provide a high degree of transmission of specified wavelengths for use in laser applications or safety needs. DSI’s proprietary process produces coatings that can withstand 25 MW/cm2 @ 1064nm or 4.5 J/cm2 with a 10ns pulse @1064nm
