Technical Field

[0001] This utility model relates to the field of electronic component testing technology, and in particular to a handheld laser emitter testing instrument. Background Technology

[0002] With the continuous development of the power grid and the continuous increase in voltage levels, the electric field is becoming larger and larger. Traditional power supply (DC power supply) is easily disturbed by the high voltage electric field. However, by using laser light, it can be unaffected by electric field interference. Laser power supply is gradually becoming an important power supply method in the power system.

[0003] The power supply level of a laser emitter directly affects the stability of a power system. Power attenuation or malfunctions in the laser emitter require comprehensive load testing of the entire equipment, a complex, inefficient process that makes it difficult to pinpoint the fault. Therefore, there is an urgent need for a testing instrument that can directly test laser emitter samples on-site, effectively eliminating potential problems in advance. Summary of the Invention
