Calcium fluoride has the characteristics of wide transmission spectrum range (180nm-8.0μm), high damage threshold, low fluorescence, high uniformity, etc. It is physically soft and easy to scratch on the surface. It is often used in laser collimation and is used as the substrate of various optical components. Plano-concave lenses can diverge light and have a negative focal length. One side is flat and the other side is concave. They are often used for beam expansion, projection and expanding the focal length of optical systems.
The XIEYI CRYO CHILLER is essential for quickly evacuating vacuum chambers for production applications. In addition to speeding up the elimination of water vapor molecules in the chamber, it also reduces the vacuum base pressure and improves the quality of vacuum coatings in many applications. Using an appropriately sized XIEYI Water vapor pump to increase the surface area of the copper or stainless steel coils can increase the yield.
