Notes

Working distance: distance between the front lens and the object. Set this distance within +/- 3% of the nominal value for maximum resolution and minimum distortion.
Working F-number (wF/#): the real F-number of a lens when used as a macro. Lenses with smaller apertures (higher wF/#) can be supplied on request.
Maximum slope of chief rays inside the lens: when converted to millirad, it gives the maximum measurement error for any millimeter of object displacement. Typical (average production) values and maximum (guaranteed) values measured at 395 nm are listed.
Percent deviation of the real image compared to an ideal, undistorted image: typical (average production) values and maximum (guaranteed) values measured at 395 nm are listed.
At the borders of the field depth the image can be still used for measurement but, to get a very sharp image, only half of the nominal field depth should be considered.
Nominal value
Measured from the front end of the mechanics to the camera flange.
With 1/1.8" (8.9 mm diagonal) detectors, the FOV of TCUV 12 XX lenses may show some vignetting at the image corners, as these lenses are optimized for 1/2" detectors (8 mm diagonal).
For the fields with the indication “Ø =”, the image of a circular object of such diameter is fully inscribed into the detector.
Indicates the availability of an integrated camera phase adjustment feature.
