Green laser alignment level

Abstract

The invention provides a green laser alignment level and belongs to the technical field of measuring instruments and devices. The green laser alignment level comprises an objective lens, a splitting instrument and an ocular lens; a laser device is connected with a circuit board through wires; laser emitted by the laser device sequentially passes through a deflecting prism II, the splitting instrument, a deflecting prism III and a deflecting prism I for transmission and is then emitted via the objective lens; the deflecting prism II is arranged between the splitting instrument and the ocular lens; the laser device is arranged right above the deflecting prism II; one end of the ocular lens is provided with an optical filter. The green laser alignment level has the advantages of, through alignment via the green laser device, being bright in beam, good in visibility, long in distance and high in resistance to stray light interference; meanwhile, by means of the optical filter on the ocular lens, a user can observe a target while enabling laser alignment and accordingly can conveniently observe a measurement target directly; besides, by means of a separated structure of the laser device and a driving circuit, the green laser alignment level can effectively solve the problem of overlarge size of a telescope.

Description

technical field [0001] The invention relates to the technical field of measuring instruments, in particular to a green laser pointing laser level. Background technique [0002] The laser level can play the role of laser pointing in the measurement, but because the laser pointing function is turned on, the laser electronic theodolite cannot observe the target object when it is in use, and the laser light source must be turned off to perform focusing observation, which brings great benefits to the user. inconvenience. SUMMARY OF THE INVENTION [0003] The invention provides a green laser pointing laser level. Using the green laser for pointing can not only capture the light spot more clearly, but also has the characteristics of bright beam, good visibility, long distance and strong resistance to stray light interference. A filter is set on the eyepiece, so that the human eye can observe the target while turning on the laser pointing, which is convenient for customers to dir...

Problems solved by technology

[0003] The invention provides a green laser pointing laser level, which uses a green laser for pointing, not only can capture light spots more clearly, but also has the characteristics of bright beam, good visibility, long distance and strong anti-stray light interference. The optical filter is set on the eyepiece, so that the human eye can observe the target while turning on the laser pointing, which is convenient for customers to directly observe the measurement target. In addition, the laser and the driving circuit are separated, which effectively solves the problem that the telescope is too large.
