Lens is a transparent glass which is bounded by two spherical surfaces. The light rays are refracted after passing through the lens. It is of two types, convex lens and concave lens.

A plano-convex lens is compose of a plane and convex surfaces, has a positive focal length.It is used for the changing between point light source and parallel beam.It is mean when the light through ...

Projectors: Concentrating light to project images. Types of Lenses: Convex Lens: Outward-curving surface resulting in the convergence of light beams.

Sometimes it is necessary to fine determine the position of the optical axes of the convex-concave lenses, such as eyeglass lenses. If the lens has not yet been processed, and its boundary has the ...
