Calcium Fluoride (CaF2) Double Convex Lenses are double convex lenses with calcium fluoride as the base material.
Calcium fluoride has a 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 for laser collimation and is used as the base of various optical components. The double convex lens focuses light into a point with a positive focal length and consists of two convex surfaces with equal radius. It is often used in imaging relay systems and imaging of objects at a limited conjugate distance. The characteristic is that the larger the conjugate ratio, the greater the aberration produced.
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.
