Variable xy-UV beam expander for high-power laser
... With this arrangement, the effects of the x-beam expander are unfelt by the y-beam expander, and vice versa. Because cylindrical elements are more difficult and costly to fabricate than spherical elements, we want to minimize the number of elements used. In addition, we desire to use standard catalo ...

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.
