WebRMI Standard Specs. Anti Reflection (AR) » Single Layer AR . 400 nm ≤ λ ≤ 2.0 µm. 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. WebFor example, N-BK7 (Schott glass) has a bulk absorption coefficient of about 0.0024 cm-1. When you think about reflectance in this way, converting between transmittance and reflectance is rather ...
