The embodiment of the invention discloses a laser emission device of a laser electronic theodolite, relating to the technical field of electronic theodolites. Stray light produced by refraction is reduced, the manufacturing error of an optical accessory is reduced, and the measurement precision is improved. The laser emission device of the laser electronic theodolite comprises a laser emitter and also comprises a laser abbe prism for steering a laser beam emitted by the laser emitter and enabling the axis of the laser beam to be consistent with the collimation axis of the laser electronic theodolite, wherein the laser abbe prism comprises an abbe prism and a laser steering lens adhered to the abbe prism; the laser beam emitted by the laser emitter is incident into the laser steering lens and then is emergent from the abbe prism after being steered through the laser steering lens. The laser emission device is applied to the electronic theodolite.
Description
technical field [0001] The invention relates to the technical field of electronic theodolite, in particular to a laser electronic theodolite and a laser emitting device thereof. Background technique [0002] Theodolite is a special instrument for measuring horizontal and vertical angles. With the development of science and technology, the mechanical structure and reading method of theodolite are also gradually perfected and improved. Its reading method has developed from the earliest metal-plated vernier reading method to the optical reading method of the optical theodolite. With the requirement for its accuracy, it has developed into a photoelectric incremental and absolute code disc electronic theodolite. [0003] The production of laser electronic theodolite is the user's further pursuit of convenient operation. The main difference between the laser electronic theodolite and the optical electronic theodolite is that the laser electronic theodolite is equipped with a lase...
