K9 Plano Concave (PCV) Lenses are plano concave lenses based on K9 optical glass.
K9 optical glass is an excellent wide-spectrum optical material with high transmittance in the 350nm-2000nm band. It has high hardness, can withstand a variety of physical and chemical stimulations, and has low bubble and impurity content. Therefore, it is often used as a base material for various optical components. Plano concave lenses can diverge light, 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.
