Technical Field

[0001] The utility model relates to the technical field of semiconductor laser detection, in particular to a positioning device for semiconductor laser detection. Background Art

[0002] Semiconductor refers to materials with electrical conductivity between conductors and insulators at room temperature. Semiconductors are used in integrated circuits, consumer electronics, communication systems, photovoltaic power generation, lighting, high-power power conversion and other fields. For example, diodes are devices made of semiconductors. Semiconductor lasers, also known as laser diodes, are lasers that use semiconductor materials as working substances. Due to differences in material structure, the specific process of generating lasers of different types is relatively special. Common working substances include gallium arsenide, cadmium sulfide, indium phosphide, zinc sulfide, etc. There are three excitation methods: electrical injection, electron beam excitation and optical pumping. When detecting semiconductor lasers, a reflector is required. When fixing the reflector, a positioning device for semiconductor laser detection is required.

[0003] Today's semiconductor laser detection positioning devices can basically meet people's usage needs, but there are still some problems. The specific problems are as follows:
