CaF₂ Infrared Transmission Windows are high-performance optical components made from calcium fluoride (CaF₂), offering excellent infrared (IR) transmission from 0.13µm to 10µm. These windows feature low absorption, high damage threshold, and superior resistance to thermal shock, making them ideal for IR spectroscopy, thermal imaging, and laser applications. Their durability and chemical stability also make them suitable for harsh environments.
