Resolving Chromatic Aberration Since no one lens can focus different light wavelengths at a single point, there’s a need to use multiple convex and concave lenses made from different types of ...

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 ...

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.

Convex and concave lenses can both be used to correct defects of vision. The most commonly occurring defects of vision are ‘short sightedness’ and ‘long sightedness’. People who are ...
