TC series
0.025 - 2 x

Key advantages

  • High telecentricity for thick object imaging.
  • Nearly zero distortion for accurate measurements.
  • Excellent resolution for high resolution cameras.
  • Simple and robust design for industrial environments.
  • Easy filter insertion.
  • Detailed test report with measured optical parameters.

Which telecentric lens is right for my application?

It depends on your detector resolution and the size of the sample to be inspected: our Imaging lens selector will guide you through all the possible sample/lens/detector combinations.

  1. Object field of view (mm x mm). For the fields with the indication "Ø =", the image of a circular object of such diameter is fully inscribed into the detector.
  2. 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.
  3. Working f-number (wf/N): the real f-number of a lens in operating conditions.
  4. Maximum angle between chief rays and optical axis on the object side. Typical (average production) values and maximum (guaranteed) values are listed.
  5. Percent deviation of the real image compared to an ideal, undistorted image. Typical (average production) values and maximum (guaranteed) values are listed.
  6. 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 3.45 μm.
  7. Object side, calculated with the Rayleigh criterion with λ= 520 nm
  8. If not available, phase adjustment can be supplied upon request (except for TC23004, TC23007,TC23009, TC23012).
  9. Measured from the front end of the mechanics to the camera flange.

Ordering information

It's easy to select the right lens for your application: our part numbers are coded as TC xx yyy, where xx defines the camera sensor size (13 = 1/3″, 12 = 1/2″, 23 = 2/3″) and yyy refers to the horizontal field of view (FOV), in millimeters. For instance, a TC12064 features a field of view of 64 (x 48) mm with a 1/2″ camera sensor.
