| description | The invention discloses a lens collimation device, which comprises a calibration assembly and a collimation assembly, and is characterized in that the calibration assembly is used for determining a main light path where a to-be-collimated lens is located and enabling emitted light of the collimation assembly to coincide with the main light path; the collimation assembly comprises a laser device, a first slit and a lens assembly which are arranged in sequence, laser emitted by the laser device enters the lens assembly after passing through the first slit and then enters the to-be-collimated lens after passing through the lens assembly, and after incident light is reflected by the to-be-collimated lens and the lens assembly, imaging light spots are formed in the first slit; and the deflection angle of the to-be-collimated lens relative to the main light path is determined according to the distance from the imaging light spot to the center of the first slit and the length of the optical path between the first sl |
