Abstract
A simple, low cost, reliable and non-electronic boresight tester was developed for use with military laser designators and range finders. Boresight testing is accomplished by attaching this device to the output end of a laser designator and checking the position of crossed green lines projected on the reticle pattern of the sighting telescope. The device uses a second harmonic generation (SHG) crystal and a corner cube reflector to convert a small portion of the infrared energy to visible green energy. This green energy forms a cross pattern imaged on the reticle by the objective lens of the laser systems under test. Cesium dihydrogen arsenate (CDA) was chosen as the best SHG for this application. Initial tests have shown the green cross pattern to be clearly visible and sufficiently bright far below the eye-safe level.
