| Zusammenfassung: | The utility model discloses laser energy calibration source equipment, which is used for generating infrared laser serving as an energy calibration source and comprises a laser generator, an optical shutter device and an energy attenuation device. The laser generator is used for generating infrared laser; the optical shutter device comprises a driving element and a first reflecting mirror, and the first reflecting mirror comprises a first reflecting surface and two side surfaces adjacent to the first reflecting surface; the driving element is used for driving the first reflector to rotate; when the first reflecting mirror rotates to a first position, the first reflecting mirror leaves the light path of the infrared laser; when the first reflecting mirror rotates to the second position, the first reflecting mirror is located in the light path of the infrared laser, and the first reflecting surface can change the propagation direction of the infrared laser; the energy attenuation device is provided with a refle |
