... At infinite conjugate with a typical glass singlet, the plano-convex shape (q = 1), with convex side toward the infinite conjugate, performs nearly as well as the bestform lens. Because a plano-convex lens costs much less to manufacture than an asymmetric biconvex singlet, these lenses are quite pop ...

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.
