K9 Double Convex Lenses

K9 Double Convex Lenses are double convex lenses with K9 optical glass as the base material.

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, so it is often used as a base material for various optical components. Double convex lenses focus light into a point with a positive focal length and consist of two convex surfaces with equal radius. They are 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.

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.
