By Dan Fiore, Vice President Polymer optics are being used in a much wider array of applications as the manufacturing processes becomes more refined and the variety of polymers available for unique applications increases. Polymer optics in their virgin form (as molded, machined or diamond-turned) are still very soft and fragile. To overcome this obstacle, polymer material suppliers have been working with enhancements at the resin level, but such improvements have not yielded the results needed to sustain polymer optics in the most severe environments. Multiple deposition techniques can be used to help make polymer optics more robust. Among the…

Everything You Ever Wanted to Know About Optical Coatings, but Were Afraid to Ask
July 10, 2019
An anti-reflective (AR) coating is a type of optical coating applied to the surface of an optical element to reduce surface reflection. In typical optical systems, this improves the efficiency since less light transmission is lost due to reflection. In complex systems the reduction in reflectance also improves the contrast of the image by elimination of stray light. The primary benefit of an AR coating is the elimination of the reflection itself, while promoting the transmission of light waves at intended wavelength ranges. With over 90 years of thin-film design experience on staff, chances are good we can design whatever…
