Anti-Reflective (AR) Coatings & Filters

(click on thumbnail to enlarge)

The reflectivity of an optical surface can be reduced by the addition of one or more non-absorbing dielectric films. An AR film will also enhance transmission in a series of optical components.

About AR

• A single layer (quarter wave) of MgF2 will typically reduce reflectivity (glass with a 1.52 index) from 4% to 1.5%
• A multi-layer AR design can reduce reflection from 4% to .3% in the visible
• A "V" design can reduce reflection to .1% across a narrow band of wavelength
• AR coatings can be designed to function in specific bands such as UV, IR and

Features

• Tight Tolerance (+-5nm at 50% transmission)
• Glass or plastic Substrates
• Volume Production ( fourteen 96" diameter vacuum PVD chambers and an inline sputtering system)
• Short Lead Times
