Mgf2 coating
WebbVisible (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 ... WebbSee Answer. Question: As an engineer you have been asked to design a quarter-wavelength anti- reflective coating (ARC) to reduce the reflectance of 550 nm wavelength light from a silicon (Si) surface. The material at your disposal is magnesium fluoride (MgF2) which has a refractive index of 1.38. Assume the refractive index of Si is 3.70.
