Lens - Wikipedia

Lenses are classified by the curvature of the two optical surfaces. A lens is biconvex (or double convex, or just convex) if both surfaces are convex.If both surfaces have the same radius of curvature, the lens is equiconvex.A lens with two concave surfaces is biconcave (or just concave).If one of the surfaces is flat, the lens is plano-convex or plano-concave depending on the curvature of the ...

Understanding a Converging Lens or Convex Lens

The effective diameter of a spherical lens is called its aperture. It determines the amount of light that passes through the lens. To help understand the refraction of light through a convex lens, imagine a convex lens as an arrangement of a number of portions of triangular prisms with a very small glass slab at the center. The base of each ...

RP Photonics Encyclopedia - lenses, wavefront curvature ...

For most lenses, the produced wavefront changes arise from the curvature of at least one of the surfaces. For the typical biconvex lens (i.e., a lens with two convex surfaces) as seen in Figure 2, the optical phase delay for light getting through the lens near its center is larger than for light propagating further away from the center, where the lens is thinner.
