ABSTRACT:
There is disclosed a method of positioning an optical subassembly for testing includes positioning an optical subassembly within a capture zone on a support surface of a test fixture. At least two probes engage surfaces of respective ones of precisely located fiducials in a surface of the optical subassembly. A third probe contacts a surface of the optical subassembly, which in a preferred embodiment may be another fiducial in the surface of the optical subassembly. Upon engagement of the probes with surfaces of respective fiducials and movement of the probes further into respective fiducials, the optical subassembly is translated into more precise alignment with optics of the test fixture.
