Bi-telecentric lenses for matrix detectors up to 2/3″ Download flyer

TC series bi-telecentric lenses represent the key component of any measurement system powered by machine vision: these lenses can truly take advantage of high-resolution detectors such as 5 Mpx - 2/3″, acquiring images with exceptional fidelity and precision.

Opto Engineering bi-telecentric design allows these optics to achieve pure telecentricity: no magnification change occurs when moving away or towards the subject, making TC series ideal for measurement applications of mechanical parts ranging from extruded aluminium profiles to tiny clock gears.

No other lenses can offer the same optical performances in terms of telecentrity and absence of distortion: additionally you can further enhance depth of field and optical accuracy by pairing our TC lenses with LTCLHP telecentric illuminators.

All of our TC lenses are rigorously tested and supplied with a detailed Test Report: We guarantee that 100% of our TC lenses meet or exceed our written specifications.
Opto Engineering TC series offers the best performance to price ratio available today and is the ideal choice when no compromise can be accepted in terms of reliability and ease of use.

Additionally we supply useful accessories including CMHO clamping mechanics and CMPT mounting plates: mechanical support systems for easy integration in industrial environments, where a solid and secure assembly is mandatory.

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.

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 millirad, 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 5.5 μm.
  6. Measured from the front end of the mechanics to the camera flange.
  7. With 1/1.8″ (9 mm diagonal) detectors, the FOV of TC12 yyy lenses may show some vignetting at the image corners, as these lenses are optimized for 1/2" detectors (8 mm diagonal).
  8. For the fields with the indication "Ø =", the image of a circular object of such diameter is fully inscribed into the detector.

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 TC 12 064 features a field of view of 64 (x 48) mm with a 1/2″ camera sensor.
