Calcium Fluoride Optical Windows are high-performance optical components known for their excellent transmission from ultraviolet (UV) to infrared (IR) wavelengths (180 nm – 8 μm). With low refractive index, high damage threshold, and exceptional resistance to thermal shock, CaF₂ windows are widely used in laser systems, spectroscopy, infrared imaging, and UV optics. These optical windows offer superior optical clarity and durability, making them ideal for demanding applications in aerospace, medical technology, and scientific research. Custom sizes and coatings are available to meet specific requirements.
