Specialized LPCVD Thin Film Coating Process For Complex Shapes/Surfaces

Deposition Sciences, Inc. (DSI®), global manufacturer of highly durable thin film optical coatings, announces the enhanced capability to apply highly specialized,durable coatings onto extremely complex shapes and multifaceted surfaces. Utilizing DSI’s proprietary IsoDyn™ LPCVD (low pressure chemical vapor deposition), this method is ideal for coating almost all types of optical glass crystalline materials, ceramics, and metals. It is also ideal for coating a wide variety of unusual geometries: from ball lenses to dome windows; from optical fibers to cold mirror reflectors.

Director of marketing and sales, Michael Newell, notes, “We are very excited to announce this enhanced capability in uniform, optical thin film coatings. DSI’s IsoDyn LPCVD process, a high temperature process (approx. 500 degrees C), is used in the manufacture of micro-optics, interference filter coatings (such as single wavelength, dual band, and broadband AR), cold mirrors, conductive coatings and dichroics. Our enhanced method is permitting exceptionally conformal coatings on many complex substrate geometries.

About DSI
Deposition Sciences, Inc. (DSI) – Santa Rosa, CA - For over 25 years, Deposition Sciences has produced the most durable optical thin film filter coatings in the industry.  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-infrared (LWIR).  At theheart of these coating capabilities for optics and other thin film technologies are DSI’s patented MicroDyn® reactive sputtering technology enabling superior multilayer thin film coatings, and the company's IsoDyn LPCVD method that permits exceptionally conformal optical coatings on complex shapes and sizes.
