One type of optical coating is an anti-reflective coating, which reduces unwanted reflections from surfaces, and is commonly used on spectacle and camera lenses. Another type is the high-reflector coating , which can be used to produce mirrors that reflect greater than 99.99% of the light that falls on them.
Optical filtering was first done with liquid-filled, glass-walled cells; [citation needed] they are still used for special purposes. The widest range of color-selection is now available as colored-film filters, originally made from animal gelatin but now usually a thermoplastic such as acetate, acrylic, polycarbonate, or polyester depending upon the application.
