High-Transmission Magnesium Fluoride Windows
High-Transmission Magnesium Fluoride (MgF₂) Windows are ideal for applications requiring excellent optical clarity across a broad wavelength range. MgF₂ windows offer high transmission from the deep ultraviolet (UV) at 120nm to the infrared (IR) at 7µm, making them perfect for UV, visible, and IR optical systems. With outstanding durability, low refractive index, and resistance to thermal and mechanical shock, these windows are widely used in spectroscopy, laser systems, and aerospace applications. Custom sizes and coatings are available to meet specific optical requirements.
