4.000x telecentric lens for detectors up to 2/3″, WD 71.1 mm

Working distance: distance between the front end of the mechanics and the object. Set this distance within ±3% of the nominal value for maximum resolution and minimum distortion. Working f-number (wf/N): the real f-number of a lens in operating conditions. Measured from the front end of the mechanics to the camera flange.
