Abstract

The invention relates to the technical field of optical measurement, and discloses a theodolite with an inner beacon. The theodolite comprises a telescope (110) and a vertical shaft (108), and is characterized in that the telescope is composed of an objective lens (101), a focusing lens (102), a visual reticle (103), an eyepiece (104), a reflective mirror (105), an inner beacon reticle (106) and an illuminating lamp (107); the telescope is mounted right above the vertical shaft (108) and can rotate by 360 degrees along with the vertical shaft, and the center of the vertical shaft (108) is the center of the theodolite; the telescope is composed of a visual aiming light path and an inner beacon light path which are axially overlapped, and the left-right symmetry axis of a virtual image (109) is overlapped with the center of the instrument by adjusting the position of the inner beacon reticle (106). The invention has the following main beneficial effects: the center of the objective lens and the center of the instrument are accurately superposed, so that the precision is high, aiming is easy, and the aiming precision in high-precision measurement is ensured.

Description

technical field [0001] The present application relates to the technical field of optical measurement, in particular to a theodolite with an internal target. Background technique [0002] Theodolite is a measuring instrument designed to measure horizontal and vertical angles based on the principle of angle measurement. It is divided into two types: optical theodolite and electronic theodolite. The most commonly used one is the electronic theodolite. The theodolite is the mechanical part of the telescope that allows the telescope to point in different directions. The theodolite has two mutually perpendicular rotation axes to adjust the azimuth and horizontal height of the telescope. A theodolite is a goniometric instrument equipped with an alidade, a horizontal dial and an index for reading, and a vertical dial and an index for reading. Theodolite is a precision measuring instrument used to measure angles in survey tasks, and can be used for angle measurement, engineering st...
