Abstract

The invention relates to an azimuth standard lens based on a roof prism. The azimuth standard lens comprises a mounting base of the optical azimuth standard lens and the high-precision roof prism, wherein the high-precision roof prism is mounted in the mounting base of the optical azimuth standard lens; a cylindrical structure at the rear part of the mounting base of the azimuth standard lens is mounted in a round hole of a mounting plate; a horizontal leveling mechanism on the mounting plate is mounted on one side of the mounting base of the optical azimuth standard lens; one end of the mounting plate is hinged with the mounting base of the optical azimuth standard lens, while the other end is mounted on the mounting base of the optical azimuth standard lens through an azimuth adjusting mechanism; and two azimuth springs are arranged between the mounting plate near one side of the azimuth adjusting mechanisms and the mounting base of the optical azimuth standard lens. The azimuth standard lens based on the roof prism is reasonable in design and flexible to operate. The azimuth and level adjustment of the azimuth standard lens is simple and quick; and the azimuth standard lens can reduce the setup difficulty of an auto-collimation theodolite, improve the efficiency and ensure the accurate mounting azimuth of the device.

Description

technical field [0001] The invention relates to the field of optical devices, in particular to an azimuth reference mirror based on a roof prism. Background technique [0002] The optical azimuth reference mirror refers to a high-precision optical device that uses the normal of the optical mirror to represent a specific azimuth edge. The optical azimuth reference mirror is mainly used in the production, test and verification places of inertial equipment, and at the same time, it is installed at the position that needs to represent the azimuth reference of the carrier. The optical azimuth reference mirror is mainly composed of an optical reflector and an installation base. The optical mirror provides high-precision optical reflection normal, and the installation base provides the installation reference for the optical mirror and ensures that the optical azimuth reference mirror can be stably installed on other equipment or bases. The existing ordinary optical azimuth refere...
