Spherical lenses can be classified by shape and function into plano-convex lenses, plano-concave lenses, biconvex lenses, biconcave lenses, and meniscus lenses. They can also be categorized by application into single lenses and cemented lenses. We offer spherical lenses in various materials, such as Si, ZnS, ZnSe, Glass (AMTIR - Amorphous Transmissive Radiation Material), Aluminum, Calcium, Fluoride, Magnesium,GaAs. We maintain a large inventory of standard lenses available for immediate delivery, and can also customize various optical lenses according to your application requirements
