WebFig 15. Measurement by Using Fixed Focal Length Lens and Telecentric Lens From the figures above, we can easily observed the performance of image quality (distortion) of using telecentric lens is much better than using fixed focal length lens. The distortion vs. image height plot of telecentri lens is also provided below: Fig 16. WebThe function of the objective lens is to form a magnified image of up to about 40× in the object plane of the intermediate or first projector lens. A small part of this image then forms the object for the first projector lens, which gives a second image, again magnified in the object plane of the second projector lens.
