The Shear Plate or Collimation Tester is an extremely
simple means to test the collimation of light beams especially from laser
sources.
Shear
plates are ideally suited to determine the proper adjustment for a laser
collimation system. They can also be used to measure wavefront radius of
curvature, determine wavefront symmetry, measure the power of
long-focal-length optics and in some cases analyze wavefront aberrations.
