These uncoated windows operate across a wavelength range from ultraviolet (200 nm) to infrared (8.0 μm), with high transmittance throughout the entire spectral range. For details, see the transmittance curve. The inherent low absorption and high damage threshold of CaF2 make these windows suitable for free-space laser-related applications. Additionally, CaF2 features low dispersion (Abbe number 95) and low fluorescence, along with excellent water resistance, chemical resistance, and heat resistance. However, CaF2 may degrade when used in high-humidity environments if the temperature exceeds 600°C. CaF2 material is prone to deliquescence in highly humid environments; it is recommended to maintain the operating environment at 25% humidity and 20°C. Excessive ambient temperature will accelerate deliquescence. After each use, clean the product thoroughly and store it in a dry cabinet (25% humidity, 20°C).\n\nThis product is slightly irritating. Operators are advised to wear dust masks and rubber gloves to avoid direct hand contact with the product and to wash hands after operation. Contact and storage with acidic substances is forbidden.\u003c\/p\u003e\n\u003ch3\u003eCalcium Fluoride Windows, Uncoated, 200 nm-8.0 μm\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSubstrate Material: CaF2\u003c\/li\u003e\n\u003cli\u003eOperating Wavelength: 200 nm-8.0 um\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe low absorption and high damage threshold characteristics of CaF2 itself make these material windows suitable for free-space laser-related applications.
