TC16M series bi-telecentric lenses have been specifically designed to fit 35 mm format (36 x 24 mm) detectors with very high resolution, such as 11, 16 or 29 Mpx.

This combination is the typical choice for extremely accurate measurement of large items such as engine parts, glass or metal sheets, PCBs and electronic components, LCDs, etc.

TC16M lenses are also perfectly suitable for 4 kpx and 8 kpx linescan cameras and can be successfully used to determine the diameter of cylindrical objects: for example shafts, turned metal parts, machine tools, etc.

Besides the standard F-mount any other mechanical interface can be easily supplied upon request.

Notes

  1. 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.
  2. Working F-number: the real F-number of a lens when used as a macro. Lenses with smaller apertures can be supplied on request.
  3. Maximum slope of chief rays inside the lens: when converted to milliradians, it gives the maximum measurement error for any millimeter of object displacement. Typical (average production) values and maximum (guaranteed) values are listed.
  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 4.8 μm.
  6. Measured from the front end of the mechanics to the camera flange.
