Single Layer MgF2 Antireflective coating

MgF2 is probably the most widely used thin film material for optical coatings. It is applicable to the substrates with the refractive index from 1.45 to2.4.

Multilayer Antireflective Coatings

VAR coatings have the lowest reflectivity in a narrow wavelength band; min. reflection can be less than 0.1%. VAR are used to target a single wavelength. When selecting a suitable multilayer anti-reflection coating, the center wavelength and damage threshold must be given special attention.

Multilayer Broadband Antireflective Coating

Multilayer Broadband Antireflective coating provides higher transmission for a wide band width. It is ideal for wide wavelength range lasers. Its performance is sensitive to the change of incident angle.

Dual Wavelength Band Antireflective Coatings

DWBAR coatings are designed to reduce the reflectance at two different wavelengths range. It is often used in frequency doubling laser system for output.
