An IR Optic Designers Best Friend

November 23, 2020

Diamond Like Carbon is an Infrared Optical Designer’s Best Friend By Dan Fiore, Vice President Diamond-Like Carbon or DLC coating is an amorphous crystalline film that is conformably grown on a surface and has properties like that of a naturally occurring diamond. The film offers a low friction coefficient, is chemically inert which lends to high abrasion and corrosion resistance. One of the most unique properties of DLC is its optical performance in the infrared spectrum where it is commonly used as an anti-reflective coating. Because DLC can be applied to relatively fragile crystalline materials such as Germanium, Zinc Selenide,…

ITO for Optical Applications

October 22, 2020

By Dan Fiore, Vice President of North American Coating Laboratories One of the most unique evaporative coatings available today is Indium Tin Oxide or ITO as it is known. ITO belongs to a family of evaporative materials known as transparent conductive oxides. The family of transparent conductive oxides includes Indium Tin Oxide (ITO) as mentioned before, ITO is the industry standard for transparent conductive films as it is robust, has good sheet resistance range and respectable UV-Visible and Near IR transmission which allows for good flexibility with multiple applications. Other members of the transparent conductive oxide family are IZO (Indium…

Designing Custom Optical Coatings

September 25, 2020

Many coating vendors supply what is termed “off the shelf” coating formulas available for common substrate types and wavelength ranges. These coatings are tested and approved for a variety of applications and allow for flexibility when assisting a customer with a quick turn or an on-going coating project. Things get slightly more sophisticated when a customer has a challenging application requiring a custom designed coating formula. These scenarios may require a coating design person to engineer a single or multilayer coating in which the transmittance , reflectance , and or absorptance values are specified at a specific number or range…
