WebA concave lens is a lens that diverges a straight light beam from the source to a diminished, upright, virtual image. It can form both real and virtual images. Concave lenses have at least one surface curved inside. A concave lens is also known as a diverging lens because it is shaped round inwards at the centre and bulges outwards through the ... 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).
