Anti-reflective Coating

Anti-reflective coatings can be added to finished lenses to improve vision and appearance.

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. It is the most commonly used, low-cost anti-reflection coating, and widely used in Lens & Prism, Input & output surface.

Spectral Curves

Specifications

P/N: SAR
Single Layer MgF2 Coating
R0<1.5% @540nm
R<2% @400~700nm

V Type Multiplayer Anti-Reflective Coatings (VAR)
It can reach the lowest reflectivity at a center wavelength, and is widely used in single laser wavelength or multiple, closely spaced wavelength system.

Spectral Curves

Specifications

P/N: VAR
V Coating
0กใ incident angle, R0<0.2% at center wavelength
45กใ incident angle, R0<0.5% at center wavelength

Broadband Multiplayer Anti-Reflective Coatings (BBAR)
It is ideal for a wide range of multi-wavelength laser and white light application. Excellentperformance over a broad range of spectrum. Coating performance is sensitive to angle of incidence.

Spectral Curves

Specifications

P/N: BBAR
Broadband AR Coating
0กใ incident angle, R<0.5% @450~650nm
0กใ incident angle, R<1.0% @420~700nm
45กใ incident angle, R<1.0% @ 450~650nm
