...for specific applications. A glass coating may be used to protect the optical lens from scratches or may provide anti-reflective qualities. An anti-reflective coating is made by coating the lens with a thin film that has an index of refraction between air... Learn More about Optical Materials

...display filters and films use semi-silvered mirrors to permit the passage of specific planes of light. They remove unwanted reflections from non-metallic surfaces such as glass and water without reflecting the overall color balance. There are two...
