  1. 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.
  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. 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 3.45 μm.
  6. Object side, calculated with the Rayleigh criterion with λ= 520 nm
  7. Indicates the availability of an integrated camera phase adjustment feature.
  8. 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 TCLWD xxx, where xxx defines the magnification (050 = 0.50, 066 = 0.66, 075 = 0.75). For example a TCLWD050 features a 0.50 magnification.
