A lens contained between two circular arcs of radius R, and centers at O1 and O2 |
In
geometry, a
lens is a
shape comprising two
circular arcs, joined at their endpoints. The
Vesica piscis is one form of a symmetrical lens.
In common usage, the term "lens" is also used to describe the shape of a three-dimensional object obtained by rotating a two-dimensional lens about its narrow axis of symmetry. Such a shape is described as
lenticular.
