Planeness issues of reflecting surfaces on a cube corner retroreflector

The quantitative relationships between the emergent wave aberration, or the right angle error, and the planeness error of three reflecting surfaces on a cube corner prism are derived and present, so that the tolerance of the planeness error can be determined by the accuracy desired For a highly accurate cube comer retroreflector, the planeness error of reflecting surface, as well as the error of right angle between two reflecting surrfaces, should be paid great attention to and concerned in
