Single Layer MgF2 Anti-reflection Coating

Magnesium Fluoride is probably most widely used thin film material for optical coating. It is applicable to the substrates with the refractive index from 1.45 to 2.4. Their performance is not outstanding, but it can present a significant improvement of anti-reflection compared to an uncoated surface. For this reason, this material acts as the most popular anti-reflection coating in visible spectrum. They are insensitive to the change of incident angle.
