Telescope range finder

Abstract

The invention discloses a telescope range finder. The telescope range finder comprises a telescope object lens, a laser receiver, a display element, a laser emission module, a spectroscope set and an ocular lens set, wherein the laser receiver receives the laser emitted from the laser emission module; the spectroscope set is formed by a ridge prism, a prism separator plate, a No.1 half-pentaprism and a No.2 half-pentaprism; the shape of the No.1 half-pentaprism is similar to the shape of the No.2 half-pentaprism; the ridge prism is provided with a light input plane, a ridge plane and an output plane; the No.1 half-pentaprism is provided with a No.1 light output input plane which is also used as a reflection plane, a No.1 input output plane, and a No.1 cemented plane; and the No.2 half-pentaprism is provided with a No.2 light output input plane which is also used as a reflection plane, a No.2 input output plane, and a No.2 cemented plane. The telescope range finder enables the light paths of the telescope object lens, the laser receiver and the display element to be coaxial through the spectroscope set so as to achieve the aim of reducing the volume of the product and prism sharing.

Description

technical field [0001] The invention relates to a range finder, in particular to a telescope range finder. Background technique [0002] The range finder is an instrument designed for length and distance measurement by using the characteristics of light, sound, electromagnetic wave reflection and interference. On the basis of length measurement, the new rangefinder can use the length measurement results to perform scientific calculations on the area, perimeter, volume, quality and other parameters of the target to be measured. It is widely used in engineering applications, GIS surveys, military and other fields. scope of application. [0003] The telescope rangefinder is a branch of the laser rangefinder, or called a long-distance laser rangefinder. The telescope rangefinder generally uses the pulse method to measure the distance. The process of pulse method ranging is as follows: the laser emitted by the range finder is reflected by the measured object and then received b...
