... For a point on the axis of the optical system, all ray fans lie in the meridional plane and only one plot is needed to evaluate the system. For off-axis object points, a second plot is added to evaluate a fan of skew rays traced in a sagittal plane. Because a skew ray fan is symmetrical across the m ...

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.
