Visible (Single layer MgF2)


Single Layer Magnesium Fluoride (MgF2) is the most common anti reflection coating due to it’s performance and wide transmission range.

It is a hard, durable coating that reduces surface reflectance of BK7 from approximately 4% to less than 1.3% at the specified centre wavelength and normal incidence. Reflection losses for higher index materials such as sapphire are less than 0.5%.

Single Layer Magnesium Fluoride (MgF2) is widely used in commercial optical products and other less demanding applications.
