Description
The High-Precision MgF₂ (Magnesium Fluoride) Window is an essential optical component designed for both UV and infrared (IR) applications. With exceptional transmission properties across a wide spectral range, from ultraviolet (UV) to infrared (IR), this window is ideal for use in spectroscopic instruments, laser systems, and advanced optical imaging. MgF₂ offers excellent durability, resistance to mechanical and thermal stress, and minimal birefringence, making it an excellent choice for high-performance optical systems.
The windows can be customized with diameters up to 160 mm and thicknesses up to 50 mm to suit specific application requirements. With options for crystallographic orientations (<100>, <111>, <110>) and surface flatness polished to Lambda/10, these windows provide the precision and quality needed for critical optical applications. The MgF₂ window is widely used in UV lasers, IR spectroscopy, and imaging systems for both research and industrial applications.
