BWYT meniscus lens Introduction: One side of the meniscus lens is convex and the other side is concave. It can be a converging lens or a diverging lens, determined by the refractive index, curvature, and radius. It is widely used in photography systems, projection systems, imaging systems, optical viewfinder, laser measurement systems, and other applications. Technical parameters: Materials: optical glass and silicon, germanium, zinc selenide, zinc sulfide, fluoride, sapphire Diameter tolerance:+0/-0.01~+/-0.1mm Thickness tolerance: ± 0.01~± 0.1mm Face type: λ/ 10~ λ/ 2@632.8nm Finish: 10/5~60/40 Eccentricity:<30 "~3 ' Effective aperture:>90% Chamfer: Coating: antireflective film, bandwidth antireflective film
