Abstract

The invention relates to the field of lens technology, in particular to a double-sided telecentric lens, which includes a front-end lens barrel, a first optical lens, a second optical lens, and a first adapter, as well as a connecting lens barrel and a second adapter. Connector; the front-end lens group is fixed in the front-end lens barrel, the first rear-end lens group is installed in the first optical lens, the second rear-end lens group is installed in the second optical lens, and the connecting mirror The barrel is equipped with an intermediate lens group; the first adapter is equipped with a beam splitting prism and a first angle adjustment assembly for adjusting the angle of the beam splitting prism; the second adapter is equipped with a reflector and is used to adjust the reflection A second angle adjustment assembly for the angle of the mirror. The invention provides a double-sided double-magnification telecentric lens, which can meet the requirements of large field of view and high magnification at the same time, effectively reduces the occupied space of the lens, and reduces the path deviation of the optical path.

Description

technical field

[0001] The invention relates to the field of lens technology, in particular to a double-sided double-magnification telecentric lens. Background technique

[0002] The telecentric lens is a high-end machine vision lens, which is characterized by eliminating the problem of different magnifications caused by the inconsistency of the distance between the measured object (or CCD chip) and the lens. Due to the unique technical advantages of the telecentric lens, currently , in the measurement of mechanical parts, plastic parts, glass products and medical parts, electronic components and other high-precision testing requirements, it is especially suitable for precision measurement occasions.

[0003] At present, the market demand for telecentric lenses is increasing, and at the same time, the imaging requirements of the lens are stricter, requiring a large field of view, high detection efficiency, and high magnification to improve the demand for high-precision measu...
