Abstract: A light reflector having a corner prism mounted for pivotal movement about at least one axis intersecting the optical axis of the prism between the vertex and the base surface. The distance between the pivotal axis and the base surface is chosen in accordance with a special relationship for minimizing measurement errors due to misalignment of the prism with respect to incident light beams.
