Abstract : The patent application concerns an instrument for measuring various parameters that are analogous to the aberrations that may exist in holographic lenses and other energy diffraction apparatus. This contains a laser energy source; a pair of masks for controlling precisely the path of the light from said laser energy source, so that it may be used as a reference parameter; a rotatable mounting table for holding the holographic lens being tested in an appropriate position in the path of said reference laser light path; a microscope positioned to receive predetermined laser light rays that have been diffracted by the holographic lens being tested; and a support bench upon which all of the aforesaid elements may be mounted, so that their respective relative positions may be controlled in such manner that they form a unique geometrical configuration and combination.
