TCLWD series

Long working distance telecentric lenses for 2/3″ detectors

Tech info
Media gallery

TCLWD is a range of telecentric lenses specifically designed for electronic and semiconductor Automated Optical Inspection (AOI) and tool pre-setting machines.

All these lenses feature a working distance of 135 mm while ensuring excellent optical resolution, high telecentricity and low distortion, thus matching and even exceeding the industrial requirements for the target applications.

The long working distance allows for extra space, which is essential if you need to install illumination, pick-up tools or provide the necessary separation from hazardous production processes.

In addition to the long working distance, TCLWD optics deliver a numerical aperture large enough to take advantage of high resolution / small pixel size cameras, making these lenses a perfect match for general-purpose 2D measurement systems.

KEY ADVANTAGES

  • Long working distance
    Perfect for electronic components inspection and tool pre-setting machines.
  • High numerical aperture
    For small pixel size / high resolution detectors.
  • Easy rotational phase adjustment
    Robust and precise tuning of the lens-camera phase.
  • Full range of compatible products
    Fits LTCLHP telecentric illuminators, CMHO clamping supports and LTRN ring illuminators.
  • Detailed test report with measured optical parameters.

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/#): 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 milliradians, it gives the maximum measurement error for any millimeter of object displacement.
  4. Typical (average production) values and maximum (guaranteed) values are listed. 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 perfectly 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. Indicates the availability of an integrated camera phase adjustment feature.

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.
