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.

“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.

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