Description

Technical Field

[0001] The utility model relates to the technical field of telescopes, in particular to a zero position calibration assembly instrument for a telescope. Background Art

[0002] A telescope is an optical instrument that uses lenses, mirrors, and other optical devices to observe distant objects. It uses the refraction of light through a lens or the reflection of light by a concave mirror to converge into an image through a small aperture. This image is then viewed through a magnifying eyepiece, often called a "telescope." The primary function of a telescope is to magnify the angular width of distant objects, enabling the human eye to discern even finer details. The secondary function of a telescope is to direct the light beam, much thicker than the diameter of the pupil (maximum 8 mm), collected by the objective lens into the human eye, enabling the observer to see faint objects that would otherwise be invisible.

[0003] Currently, during the production process of binocular rangefinders, the crosshairs, emission spot, and receiving aperture of the binoculars need to be calibrated to achieve the clearest state. It is also necessary to ensure that the centers of the three are centered. The conventional operation is to make an optical eyepiece jig with a reticle as a reference for operation. However, when using this jig, the original eyepiece on the telescope needs to be removed and then the jig is installed on the telescope. After the calibration is completed, the original eyepiece needs to be installed on the telescope again. Therefore, there are the following disadvantages: when the staff calibrates the telescope, they need to frequently disassemble and assemble the eyepiece, which is cumbersome and causes the staff to waste time and effort.
