WebJan 1, 2016 · LENS TYPES There are two principal types of lenses: positive (also called converging or convex lenses) and negative (also called diverging or concave lenses). Each positive and negative lens exists in three basic types. Positive lenses are bi-convex (also called dual convex), plano-convex, and positive meniscus (see Figure 1).

WebIt is normally used to express the optical power of a lens or curved mirror, which is a physical quantity equal to the reciprocal of the focal length, expressed in metres. For example, a 3-dioptre lens brings parallel rays of light to focus at 1⁄3 metre. Web• The focal lengths f marked on the lenses are for the lenses in air. The index of refraction of air is about 1.0003 ≈1.000. The focal length f ℓ of one of these lenses in a liquid of index of refraction n ℓ is given by f ℓ = n ℓ(n−1) n−n ℓ f, (3) where n is the index of refraction of the lens material.
