Optical lens manufacturer —— Design principle and function of optical lens and brief introduction of optical lens polishing process
Optical lens is not widely used, and telecentric lens is not well known because of its mysterious color. The design principle of telecentric lens is introduced below.
Telecentric lens is a lens specially designed to correct the parallax of traditional lens. It can make the image magnification not change with the change of object distance within a certain range of object distance, which is a very important application when the measured object is not on the same object plane.
