TC2M and TC4M series

Bi-telecentric lenses for large detectors

TC2M and TC4M lenses are bi-telecentric lenses designed for detectors larger than 2/3″. TC2M lenses cover up to 1” (16 mm diagonal) detectors. TC4M lenses cover up to 21.5 mm detector diagonal and are therefore suitable for 1.2” imagers.

In order to help the selection, some of the most commonly used large matrix detectors are listed below. Select the lens that best suits your application by choosing the column where the right detector is listed and scrolling down the table until you find the field of view best matching your needs.

All the lenses listed below can be equipped with a C or F-mount interface (ordering code: part number-F for F-mount and part number-C for C-mount, e.g. TC4M 064-F for an F-mount TC4M 064 lens.

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.
  7. With KAI-08050 (22.6 mm diagonal) detectors, the FOV of TC4M yyy lenses may show some vignetting at the image corners, as these lenses are optimized for 1.2" detectors (21.5 mm)
