A sei of wedge plates required for selling up lateral shearing interferometer for laser beam collimation testing of various apertures has been suggested in order to obtain maximum sensitivity in the detection of laser beam decollimation. The wedge angle of the plate may vary from an angle of 2.5 arc-sec to 60 arc-sec whereas the suitable thickness of the wedge plate may vary from 3 mm to 66 mm depending on the size of the laser beam under test. As set of ten wedge plates is suggested for checking the laser beam decollimation of apertures varying from 3 mm to 100 mm.
