Notes

  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 7 μm.
  6. Object side, calculated with the Rayleigh criterion with λ= 520 nm
  7. FD stands for Flange Distance (in mm), defined as the distance from the mounting flange to the camera detector plane.
  8. Indicates the availability of an integrated camera phase adjustment feature.
  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 TC4Kyyy-x where yyy refers to the field of view (FOV) in millimeters and -x refers to the mount option:
-F for F-mount.
-N for M42x1 mount (flange distance FD 10.56 mm).

For example, TC4K060-N refers to a TC4K060 with M42x1 mount.
