Calcium Fluoride CaF2 Meniscus Lens

Calcium fluoride CaF2 crystals have high hardness, strong resistance to mechanical and thermal shock, and good transmittance in the ultraviolet, visible, and infrared fields. They are widely used in technology fields such as lasers, infrared optics, ultraviolet optics, and high-energy detectors, especially their excellent optical performance in the ultraviolet band. They are currently known as optical crystals in the ultraviolet cutoff band. One side of the meniscus lens is convex and the other side is concave. It can be a convergent lens or a divergent lens, determined by the refractive index, curvature, and radius together. Our company can provide a diameter of 2-300mm and a thickness of 0.12-60mm The calcium fluoride lunar lens has four major processes: rubber disc polishing, high-speed polishing, circular polishing, and CNC polishing. It has ZYGO, AFM, reflection and transmission eccentricity, 15 second angle measuring instrument, UV adhesive centering system, non-contact laser…
