Product Detail

Meniscus lenses are divided into positive meniscus and negative meniscus lenses. A meniscus lens has one side of the lens that is convex and one side that is concave. It can be a converging lens or a diverging lens, determined by the refractive index, curvature and radius together. Widely used in photographic systems, projection systems, imaging systems, optical viewfinders, and laser measurement systems.
