Specifications
Anti-Reflection (AR) coating is one of widely used optical thin-film coatings that can be applied to the surfaces of optical elements to reduce reflection and to improve transmittance within some spectral region.
Single Layer MgF2 Anti-Reflective Coatings (SAR)
Magnesium fluoride (MgF2) is probably the most widely used thin film material for optical coatings. Its performance is not outstanding but represents a significant improvement over an uncoated surface.
Multilayer Anti-Reflective Coatings (VAR)
Multilayer AR coatings can reach low reflectivity at center wavelength. It is often applied to single laser wavelength or multiple closely spaced wavelength system to guarantee the lowest loss for center wavelength. Wavelength range for Multilayer AR coatings range from 250nm to 2200nm.Center wavelength and damage threshold are important to the selection of suitable coating.
Multilayer Broadband Anti-Reflective Coatings (WAR)
In contrast to single layer MgF2 broadband AR coating, Multilayer Broadband AR coating can reach higher transmission in broadband spectrum. It is ideal for a wide range of multi-wavelength laser and white light applications. Wavelength range and reflectivity of the Multilayer Broadband AR Coating is determined by the incident angle.
Dual Wavelength Band Anti-Reflective Coatings (DAR)
This coating allows two center wavelengths radiation to pass through the substrate with high transmission. Dual Wavelength Band Anti-Reflective(AR) Coatings is often used in frequency doubling systems or multi-laser output system such as Nd:YVO4 laser(1064nm) and its second harmonic generation(SHG) of green laser(532nm).
