MgF2 & AR520

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 NIR.

Features

  • Large Format (up to 35" diameter)
  • Low Cost (large volume throughput coaters coupled with low overhead operations)
  • 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
