ABSTRACT:
An apparatus in which the alignment of an optical system is displayed, thereby enabling misalignments therein to be corrected. The alignment apparatus, in conjunction with the optical system, generates a narrow sample light image. This sample light image is displayed so as to depict the optical system misalignment. Thereafter the optical system is adjusted and a corrected sample light image produced. The corrected sample light image is once again displayed to insure that the optical system is in alignment.
