4.000 x telecentric lens with built-in coaxial illumination for detectors up to 1″

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.
