Single Layer Magnesium Fluoride (MgF2) is the most common anti-reflection coating. It is a hard, durable coating that reduces surface reflectance of BK7 from approximately 4% to less than 1.3% at the specified center wavelength and normal incidence. Reflection losses for higher index materials such as sapphire are less than 0.5%. This coating is widely used in commercial optical products and other less demanding applications.
Its performance is not outstanding but it does represents a significant improvement over an uncoated surface. For your application,please refer to its following characteristics:
Substrate coated with only a single layer of magnesium fluoride (MgF2).
Remaining reflectance is larger than a multi-layer AR (about 1.5% per surface for BK7 substrate).
Has less sensitivity to incident angle and the usable wavelength range is broad.
Sufficiently reduces the reflectivity when applied on the glass substrate which have high refractive index (about 1.8-1.9).
