A Vision Measuring Instrument Based on Telecentric Optical Technology

Abstract

The invention discloses a vision measuring instrument based on a telecentric optical technology. The visual measuring instrument comprises a shell assembly, an objective table assembly, a lens fine adjustment mechanism assembly, a standby light source support assembly, a telecentric parallel light source assembly, a lens fixing assembly, a support assembly, a double telecentric lens and an industrial camera, wherein the objective table assembly, the lens fine adjustment mechanism assembly, the standby light source support assembly and the telecentric parallel light source assembly are arrangedon the support assembly; the lens fixing assembly is arranged on the lens fine adjustment mechanism assembly; the double telecentric lens is arranged on the lens fixing assembly; the industrial camera is installed on the upper portion of the double telecentric lens; and the support is installed in the shell assembly. The visual measuring instrument has the advantages of being simple and attractive in structure, convenient to use and maintain, various in measurement function and high in measurement precision, and can be used for finely adjusting the pitch angle of an image acquisition assembly, so that the coaxiality of light rays can be kept to the maximum extent, and the measurement precision is greatly improved.
