Opto Engineering TCLWD3M Telecentric Lenses
fixed working distance telecentric lenses for sensors up to 1.1"

Opto Engineering TCLWD3M telecentric lens with a fixed working distance for sensors up to 1.1" Opto Engineering TCLWD3M lenses are specifically designed for electronic and semiconductor Automated Optical Inspection (AOI) and tool pre-setting machines. These high-resolution fixed working distance telecentric lenses feature a long working distance that provides extra space for illumination, pick-up tools, or separation from hazardous production processes.

TCLWD3M telecentric lenses, with a large numerical aperture, provide superior image quality and high resolution. These lenses are optimized for sensors with wide image circles up to 1.1" and are ideal for many general purpose 2D measurement applications. They are compatible with high-resolution/small pixel size cameras, due to their large numerical aperture.

  • Wide image circle for sensors up to 1.1"
  • Fixed working distance for consistent focus and magnification
  • Long working distance
  • High numerical aperture
  • Magnifications from 0.2 - 1 x
  • Excellent quality/price ratio

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. 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. Maximum (guaranteed) values are listed.
  5. Percent deviation of the real image compared to an ideal, undistorted image.
  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. Measured from the front end of the mechanics to the camera flange.
