Lenses as singlets, doublets and triplets in different shapes

Spherical lenses are used in many different applications, such as cameras, projectors and microscopes.

They are used to collect, focus and diverge light and are often as components of lens systems that perform an achromatic function.

Achromatics consist of two or three elements of different lenses cemented together to limit the effect of spherical and chromatic aberration.
