Materion has developed a manufacturing process for Magnesium Fluoride (MgF) which produces a highly pure, dense material form that is particularly well suited for optical coating. MgF, a low index coating material, has been used for many years in anti-reflection and multilayer coatings. It is insoluble and hard if deposited on hot substrates. Magnesium Fluoride evaporates cleanly and completely, without outgassing or spitting, and leaves a hard, uniform coating on the substrate.Information provided by Materion. |
