157.8 mm WD C-Mount telecentric Lens Opto Engineering TC12056

Bi-telecentric Lens for 1/2"-detectors, Magnification 0.114 x, C-Mount

The bi-telecentric lenses TC12056 of the TC series from Opto Encgineering are the main component of any image processing-based measuring system: These lenses can get the most out of high-resolution detectors (e.g. 5 MP - 2/3 ") and record images with exceptional image fidelity and accuracy.

technical Features TC120056:

Notes

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.
2. Working F-number (wF/#): the real F-number of a lens in operating conditions.
3. Maximum angle between chief rays and optical axis on the object side.
4. Percent deviation of the real image compared to an ideal, undistorted image: typical (average production) values and maximum (guaranteed) values are listed.
5. 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. Pixel size used for calculation is 5.5 μm.
6. or the fields with the indication "Ø =", the image of a circular object of such diameter is fully inscribed into the detector.
7. If not available, phase adjustment can be supplied upon request (except for TC23004, TC23007, TC23009, TC23012).
8. Measured from the front end of the mechanics to the camera flange.
