Opto Engineering TCZEL Telecentric Zoom Lenses
integrated with two Optotune liquid lenses

Opto Engineering TCZEL telecentric zoom lens with dual liquid lens technology
Opto Engineering TZCEL telecentric focus tunable zoom lenses combine the precision of telecentric optics with the flexibility of zoom lenses and the speed of Optotune liquid lenses. These lenses provide superb color correction in white light within the nominal magnification and working distance ranges, with improved performance in monochrome, particularly in the extended range. Their innovative design provides the ability to adjust both the magnification and the working distance. TCZEL lenses excel in machine vision application tasks such as inspection, and precision measurement of parts.

  • Flexibility of zoom lenses and the speed of two integrated Optotune liquid lenses
  • Magnifications from 0.18 - 0.55 x
  • Adjustable magnification and working distance.
  • No moving optical mechanical parts for reduced wear

Opto Engineering telecentric lenses include a wide variety of lenses for area and line scan cameras. Contact us if you would like help choosing the right lens for your industrial machine vision applications.

Notes

  1. Working distance: distance between the front end of the mechanics and the object, reported at nominal range of the liquid lenses; maximum excursion may be larger.
  2. Working f-number (wf/N): 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.
  5. At the borders of the field depth the image can be still used for measurement but, to get a perfectly sharp image, only half of the nominal field depth should be considered. Pixel size used for calculation is 3.45 μm.
  6. Object side, calculated with the Rayleigh criterion with λ= 520 nm
  7. Typical at 30°C, 0 to ±250 mA step.
  8. Indicates the availability of an integrated camera phase adjustment feature.
  9. Measured from the front end of the mechanics to the camera flange.

Additional Notes

  1. Performances guaranteed when used with vertical optical axis; when used with horizontal optical axis performances drop due to gravity induced aberrations of the liquid lens.
