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.
