Abstract:
A testing system comprising:a. a handling system for automatically loading and positioning within a given tolerance each of a plurality of laser diode sub-assemblies, the handling system comprising: i. a loading device for automatically loading and unloading each of the laser diode sub-assemblies into and out of one of one or more collets; and ii. a carousel including one or more more nests, each nest for supporting one of the one or more collets, wherein the carousel moves each collet from a loading position, to one or more testing positions, and to an unloading position; b. an optical system for automatically receiving each laser diode subassembly from the handling system and automatically performing one or more tests to measure functionality of each laser diode sub-assembly; c. a detection system for detecting characteristics associated with one or more tests performed by the optical system for each laser diode sub-assembly; and d. a control system for automatically receiving detected characteristics from the detection system, comparing the detected characteristics to stored expected characteristics for a properly functioning laser diode sub-assembly thereby forming a comparison, and providing control instructions to the optical system based on the comparison.
