Another advantage of using Telecentric Lenses in metrology applications is that Telecentric Lenses typically have lower distortion values than Fixed Focal Length Lenses. Distortion causes the actual position of an object to appear as though it is in a different location, which can further decrease measurement accuracy (see Distortion for more information). how to take note on a reading As you move an object closer to a lens of any focal length, the resulting image will show signs of distortion due to the changing angles of light entering the lens.
