Single Layer MgF2 Antireflective Coatings (Part No.: SAR)

Magnesium fluoride 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. Because its index is too high to provide a good impedance match at the air-glass interface.

l R 0 <1.5%@540nm l R<2%@400-700nm	l R 0 < 2.0%@540nm l R<3.0%@400-700nm

Multilayer Antireflective Coatings (Part No.: VAR) 

 Such antireflective coatings can reaches the lowest reflectivity at a center wavelength. It is often applied to single laser wavelength or multiple, closely-spaced wavelength system to guarantee the lowest loss for center wavelength. We can provide such coating with center wavelength from 250nm to 2200nm. When selecting a suitable multilayer antireflective coating, the center wavelength and damage threshold must be payed attention to.

l R0<0.25%@1064nm	l R0<0.5%@1064nm

Multilayer Broadband Antireflectance Coatings(Part No.: WAR)

Different from single layer MgF2 broadband antireflective coating, the multilayer Broadband antireflective coating can reaches higher transmission for broadband spectrum. Therefore, it is the ideal for a wide range of multi-wavelength laser and white light application. Please notified that the wavelength range and reflectivity of the coating are obviously changed according to the incident angle.

l R<0.6%@450~650nm l R<1.0%@420~700nm	l R<1.0%@450~650nm

Dual Wavelength Band Antireflective Coatings(Part No.: DAR)      

  This coating allows two center wavelengths radiation pass through the substrate with high transmission. This coating is often used in frequency doubling systems or the other muti-laser output systems, as the Nd: YVO4 laser (1064nm) and its second harmonic generation (532nm) green laser.

l R0<0.25%@1064nm l R0<0.5%@532nm	l R<0.5%@1064nm l R<0.8%@532nm
