Applications
MgF₂ is widely used in UV lithography systems, laser spectrometers, and infrared imaging equipment, especially suitable for precision optical devices requiring low reflectivity and broadband transmittance.
Key Features
MgF₂'s crystal structure gives it high transmittance from the ultraviolet (150nm) to the mid-infrared (8μm) bands, extremely low absorption loss in the deep ultraviolet band, and also excellent chemical stability and weather resistance, allowing it to maintain optical performance in humid or corrosive environments. MgF₂ has low thermal expansion and a high laser damage threshold; it is not only widely used as the core material for anti-reflection (AR) coatings to minimize surface reflection, but can also be fabricated into UV lenses, optical windows, and prisms.
