WebWhen applied at high temperatures, MgF2 becomes a hard, durable coating that meets all standard MIL requirements. It exhibits broadband characteristics and can be applied on a variety of substrates for use in spectral regions from the UV to the NIR. MgF2 has the best performance:cost ratio of any antireflection coating. Reflectivity (per surface) Weband part is transmitted. Such coatings always have high reflection for S-polarization radiation and high transmission for P-polarization radiation. The main application this coating is used for is beamsplitters. It is also widely used in inspection systems, so that we can get radiation in measurements of datum light. R = 90.0% ± 1.0% @ 1064nm

Reflectivity of mgf2

WebFor more than four decades, Acton Al+MgF 2 high-efficiency coatings have set the standard for broadband UV and VUV reflectance. These coatings are designed to offer industry-leading reflectance down to 120 nm, with excellent broadband reflectance throughout the visible and near-infrared ranges. WebMgF2 has the best performance/cost ratio of any anti-reflection coating available today. Narrowband AR ("V") Coatings (AR-V) Commonly referred to as a "V" Coating due to its spectral shape, Narrowband AR Coatings are the simplest of the multilayer coatings and are used whenever the application involves a single wavelength.

WebSee the answer. In the figure below, a glass lens is coated on one side with a thin film of magnesium fluoride (MgF2) to reduce reflection from the lens surface. The index of refraction of MgF2 is 1.38; that of the glass is 1.50. Assume that the coating minimizes the reflection of light of wavelength 569 nm at normal incidence. WebMagnesium fluoride (MgF2) is probably the most widely used thin film material for optical coatings. Its performance is not outstanding but represents a significant improvement over an uncoated surface. Multilayer Anti-Reflective Coatings (VAR) Multilayer AR coatings can reach low reflectivity at center wavelength.
