Telelens with focal length of 150 mm provides 1:1 magnification with a 160-mm scanlens. It has a 1/2-in. sensor, which gives a 6 × 4-mm field of view. The lens has a large focusing range to compensate for the focal length difference between laser wavelength and inspection wavelength. The telelens design offers a compact envelope and allows integration of a beamsplitter cube for coaxial illumination through the lens.
