Abstract
An alignment system for a two-way laser communication station. Each station is constructed so that the optical receiver portion is pre-aligned to be parallel to the cabinet base structure, and a multiple point screw adjustment is used to align the laser source and columnating lens assembly with the cabinet after the weatherproof enclosure is sealed. Actual alignment is accomplished by making the adjustment while operating two stations as complimentary transmitters and receivers over a long test path which has been optically aligned.
