Uses of concave lens in lasers

Different types of scanners, medical equipment, and CD and DVD players use laser beams. As the laser beams are highly focused, they are dispersed so that the equipment works properly. Small concave lenses are used which widen the laser beam to sharply access a specific area.

Use of concave lens in cameras

To improve the quality of photographs, combinations of convex and concave lenses are widely used by camera manufacturers. When only a convex lens is used as the primary lens of a camera, it causes distortions in the photos, which is called chromatic aberrations. Combining both concave and convex lens eliminated the undesirable effects. [/tex]

Used in flashlights

Concave lenses are also used in flashlights to magnify the light produced by the source. The light rays fall on the hollowed side of the lens, and the light rays diverge on the other side. This increases the radius of the light source and thus provides a wider beam.
