CF16 CaF2 Calcium Fluoride Vacuum Window

This product is a high-performance optical accessory specifically developed to meet the demands of ultraviolet and infrared optical observation and measurement in high-vacuum environments. With “broad-spectrum transmittance, high transmission with low noise, and corrosion resistance and stability” as its core design objectives, it strikes an optimal balance between superior optical performance and compatibility with high-vacuum conditions. It is ideally suited for a wide range of vacuum optical experiments conducted in university, research institute, and corporate laboratories, providing stable and reliable hardware support for applications such as spectroscopic analysis and optical metrology.
Key features:
1. Broadband High Transmittance Leadership: Custom-made using high-purity calcium fluoride (CaF₂) optical substrates, offering exceptional transmittance across the ultraviolet to infrared spectral range with no significant absorption peaks, thereby meeting the demands of broadband optical observation and detection applications.
2. Reliable vacuum compatibility: Equipped with a standard CF16 flange and a high-vacuum sealing structure, it can achieve leak-free sealing when paired with oxygen-free copper gaskets, eliminating vacuum loss and ensuring the chamber’s ultimate vacuum level.
3. Corrosion-resistant, durable, and stable: Calcium fluoride material is resistant to corrosion by weak acids, weak bases, and organic solvents, exhibits excellent thermal stability, is less prone to moisture absorption and cracking, thereby extending equipment service life and ensuring the purity of experimental samples and optical data.
4. Convenient and Easy Installation: The compact, standardized design ensures a small footprint and straightforward installation, eliminating the need for additional adapter components. It can be directly matched with vacuum chambers of corresponding specifications and is compatible with various laboratory workstations and equipment layouts.
