Testing and adjustment system for opto-electronic device - uses two units spaced relatively close with high accuracy but with approximate axial alignment

摘要

The system for a device with several optical axes and high parallelity requirements e.g. for weapon sights comprises two separate units. One of these incorporates the measuring appts., while the other comprises a multiple mirror group. When the system is set up the distance between the two units has to be set accurately, but their axial alignment can be set approximately. Pref. the first unit has a holder for the test device in front of which a collimator with a deflection mirror is positioned. A test target is fed to the test device via the spaced mirror group and the collimator.
