Magnesium Fluoride Optical Windows – High-Performance Optical Components
Magnesium Fluoride (MgF₂) optical windows are highly durable, low-dispersion components ideal for a wide range of optical applications. With excellent transmission from the deep ultraviolet (UV) to the mid-infrared (IR) spectrum (120nm–7µm), MgF₂ windows are widely used in UV imaging, spectroscopy, and laser systems. Their high resistance to thermal and mechanical shock makes them suitable for harsh environments.
We offer precision-customized Magnesium Fluoride Optical Windows with superior surface quality and coating options to meet your specific optical requirements. Contact us today for high-performance MgF₂ optical solutions!
