cylindrical lens design

Description

A spherical-cylindrical lens is a lens that is shaped like a cross-section of a sphere and cylinder, with the glass facing the inside of the sphere. You might use this type of lens in applications where you need divided light beams or circular beams with different polarizations, or when you have multiple beam sources (such as in imaging applications) and want to focus each one at a different point.

A spherical cylindrical lens can be used for producing a converging, diverging, or doublet optical system. The lens consists of two elements - one is the concentric curved element, called the lens surface, and the other is the plano-convex cylindrical element on the side opposite to that of the lens surface.

A spherical cylindrical lens changes the direction of light passing through it. Spherical lenses and cylindrical lenses are used in a variety of applications, including cameras, microscopes, and eyeglasses.
