Abstract

The invention discloses an aiming device, which belongs to the technical field of aiming. The device comprises a transparent base, a ring grating, at least two arc gratings and a light source assembly, the ring grating and at least two arc gratings are arranged on one side surface of the transparent base, and the surface of the area where the transparent base is located at the central part of the ring grating is flat, at least Two arc-shaped gratings are arranged on the radial periphery of the ring grating at uniform intervals along the circumferential direction with the center of the ring grating as the center. The center of the arc grating is located between the arc grating and the center of the ring grating. There is a one-to-one correspondence between a beam of light and a curved grating. The invention can not only ensure the aiming effect, but also reduce the production cost of the product.

Description

technical field [0001] The invention relates to the technical field of aiming, in particular to an aiming device. Background technique [0002] In the fields of industrial measurement, structural engineering, area measurement and military affairs, targeting is a basic technology. Optical components such as complex gratings, optical lenses, mirrors and laser diodes have been used to align various targets in the visible Among the various aiming devices in the center of the area. [0003] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] Because the components of the aiming device and the temperature environment in which they are located will have a thermal effect on the wavelength and diffraction angle of the optical element, which will cause aiming errors. In order to reduce the aiming error caused by thermal effects, the optical elements are usually improved, for example, two tran...
