Cylindrical Lenses, N-BK7 Optical Glass
Description
While all lenses have one or more spherical surface, the curved surface on a cylindrical lens is shaped like a cylinder. Performance is characterized by a focal line that lies parallel to the cylindrical axis. These lenses are useful in application areas, such as optical data storage and retrieval systems for imaging linear arrays, spectroscopic instrumentation for imaging slits, and other processes involving scanning techniques. Cylindrical lenses are also frequently used with lasers to generate a narrow line of light that is used for measurement or alignment. Esco manufactures a variety of standard plano-convex N-BK7 optical glass cylinder lenses. All lenses are pitch polished for precicision surface quality and accuracy.
