What is a telecentric lens?
A telecentric lens is a special lens designed to correct the parallax of traditional industrial lenses. It can ensure that the magnification of the captured image does not change within a certain object distance range, which is especially important when the measured object is not on the same object surface. Telecentric lenses are mainly divided into object-side telecentric lenses, image-side telecentric lenses and bilateral telecentric lenses. Through the unique optical design of these lenses Rwanda Sugar Daddy, the entrance pupil is located at infinity, only receivingIt is affected by the principal ray parallel to the optical axis, thus effectively avoiding perspective errors.
Optical principles
Telecentricity Lens optical principle
The core principle of a telecentric lens is that it places an aperture diaphragm at the core of the optical system. This design allows only light rays parallel to the optical axis to be captured by the optical device. In detail:
Object telecentric lens: Place the aperture diaphragm on the image focal plane. Even if the object distance changes, the size of the photographed object will not change, ensuring the stability of the image. Image-side telecentric lens: Place the aperture diaphragm on the object-side focal plane. Although there is an error in the installation position of the CCD chip, the size of the projected image on the CCD chip remains unchanged, further enhancing the stability of the imaging.
This design of the telecentric lens eliminates the change in image reduction magnification caused by changes in object distance, thereby avoiding the traditional lens RW EscortsThe rare perspective error achieves more precise imaging.

General High Resolution Telecentric Lens
Eliminate Parallax: Through precise optical design, General High Resolution Telecentric Lens can effectively eliminate parallax and improve measurementRW Escorts‘s Correctness. The elimination of parallax means a significant reduction in image distortion and measurement errors.
High-precision measurement: with high resolution and high sensitivity, the popular telecentric lens Rwanda Sugar It can capture finer details, allowing the size measurement system to more accurately measure the size, shape and other parameters of objects.
High contrast: The quality of the image object acquired is high, and the edge image is clearly displayed, which helps the system to more accurately identify and evaluate the size parameters of the object.
