Abstract
A method and an instrument are provided for checking and adjusting the accuracy of an alignment device which transmits a collimated (e.g. laser) light beam that serves as an alignment reference. That beam generator defines a precise reference for purposes of alignment of various other forms of apparatus, often over great distance. The checking and adjusting instrument (which is totally passive) provided by this invention is precisely attached to the alignment device, temporarily, and receives the reference beam of light from the device. The instrument displays an indication of misalignment of the beam, and also aids in correcting same.
