The Focal Length of a Thin Converging Lens
... The ability of a lens to focus light is a consequence of its shape and optical density relative to that of the surrounding environment. For example, a thin converging lens, typically made from some type of glass, is fabricated into the shape of two spherical caps of relatively small curvature with t ...

Retroreflector
A retroreflector (sometimes called a retroflector or cataphote) is a device or surface that reflects light back to its source with a minimum of scattering. In a retroreflector an electromagnetic wavefront is reflected back along a vector that is parallel to but opposite in direction from the wave's source. The angle of incidence at which the device or surface reflects light in this way is greater than zero, unlike a planar mirror, which does this only if the mirror is exactly perpendicular to the wave front, having a zero angle of incidence.
