Miniature multi-spectral optical axis calibrator

Abstract

The invention discloses a miniature multi-spectral optical axis calibrator which comprises a splitting mirror assembly, an objective lens assembly, a swivel arm seat assembly, an insertion rod assembly, a fixation seat assembly, a power supply assembly and a rotating shaft. The splitting mirror assembly sleeves one end of the rotating shaft and is locked by a locking nut III. A wire jacket I is fixed on the locking nut III. A wire sleeve which is pressed by a wire jacket press ring is arranged on the wire jacket I. The objective lens assembly sleeves the other end of the rotating shaft. The swivel arm seat assembly is rotatably arranged on the rotating shaft and is located between the splitting mirror assembly and the objective lens assembly. The swivel arm seat assembly is provided with a steel ball on one end close to the splitting mirror assembly. A retaining ring I which presses the steel ball is arranged on the rotating shaft in a threaded manner. The retaining ring I is locked by a locking nut I. The insertion rod assembly is inserted into the swivel arm seat assembly and is rotatably engaged with the swivel arm seat assembly through the steel ball. The fixation seat assembly is arranged on the insertion rod assembly. One end of the power supply assembly is inserted into the insertion rod assembly. The other end is connected with the rotating shaft. The miniature multi-spectral optical axis calibrator provided by the invention has the advantages of high calibration accuracy, large coverage caliber, no color difference and the like.

Description

technical field [0001] The invention belongs to the field of optical instrument calibration, and more specifically relates to a miniature multi-spectral optical axis calibration instrument. Background technique [0002] The photoelectric sight is an instrument that projects the aiming dot or line of sight on the mirror surface of the sight by electronic imaging. The advantage of this sight is that there is no problem of parallax, regardless of the distance or angle between the shooter's eye and the eyepiece of the sight. Or the distance between the sight and the target, the aiming dot you see always falls on the aiming point, so you can quickly grab the target and shoot. [0003] With the increase in the types of photoelectric sights, there is an increasing need for an instrument that can satisfy the optical axis calibration of multiple sights at the same time. The main mirror of the traditional optical axis calibrator adopts a spherical mirror with a small aperture and a s...
