Device for calibrating the coaxiality of the optical axes

Abstract

This utility model discloses a device for calibrating the coaxiality of optical axes, aiming to solve the problems of poor repeatability, fixed and unadjustable target plates, and lack of multi-dimensional adjustment capabilities in existing technologies. This utility model includes a calibration device, a standard target plate, a multi-dimensional adjustment mechanism for adjusting the standard target plate, and a control unit. The calibration device includes: a housing; a leveling base located below the housing; and a laser emission module mounted on the leveling base via a lifting mechanism. The multi-dimensional adjustment mechanism includes: a horizontal rotation mechanism that drives the standard target plate to rotate around the vertical Z-axis; a translation adjustment mechanism located below the horizontal rotation mechanism that adjusts the position of the entire horizontal rotation mechanism in two orthogonal directions on the horizontal plane; and a pitch adjustment mechanism located between the standard target plate and the horizontal rotation mechanism that adjusts the pitch angle of the standard target plate relative to the horizontal rotation mechanism.
