TCBENCH series

Telecentric optical benches for precision measurements

Tech info
Resources

TCBENCH series are complete optical systems designed for hassle-free development of demanding measurement applications.

Each kit integrates:

  • 1 bi-telecentric lens for 2/3” detectors
  • 1 LTCLHP telecentric illuminator (green)
  • 2 CMHO mechanical clamps
  • 1 CMPT base-plate
  • 1 PTTC chrome-on-glass calibration pattern
  • 1 CMPH pattern holder

The benches come ready for use, pre-assembled and pre-aligned to assure the best accuracy that a telecentric measurement system can deliver.

The collimated light source is set in order to optimize both illumination homogeneity and relevant optical parameters such as distortion, telecentricity and resolution. For this reason these benches feature unmatched image resolution and field depth.

Opto Engineering® measures the optical performance of each TCBENCH and provides an individual test report. TCBENCH series also benefits from a special price policy, combining high-end performance with cost effectiveness.

KEY ADVANTAGES

  • Pre-assembled set-up
    Just attach yor camera, and the bench is ready for measurement
  • Best optical performances
    The bench is pre-set to provide unpaired measurement accuracy
  • Tested system
    The bench is quality tested as a whole system
  • Detailed test report with measured optical parameters

DID YOU KNOW?

TCBENCH series is now also available with new LTSCHP1W-GZ green light source, suitable for any kind of sample and specifically tailored for measuring reflective objects and objects with sharp edges.

KEY FEATURES

  1. Reduction of edge diffraction effects
  2. Enhanced illumination uniformity, especially on large FOVs
  3. Less sensitive to alignment

SPECIALTIES

TCBENCH telecentric optical assembly for machine vision applications

The benches come pre-assembled and pre-aligned to assure the best accuracy that a telecentric measurement system can deliver.

The collimating source is set in order to optimize both the illumination homogeneity and the relevant optical parameters (distortion, telecentricity, resolution).

Opto Engineering® tests the optical performances of each TCBENCH and provides an individual test report certifying the measurement accuracy of the entire system.

Coupling a LTCLHP illuminator with a telecentric lens increases the natural field depth of the lens; this is particularly true for 2/3” detector lenses where the acceptance angle of ray bundles is much larger than the divergence of the collimating source.

For this reason these benches feature unmatched image resolution and field depth. TCBENCH also benefit from a special price policy, combining high-end performances with cost effectiveness.

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 3.45 μm.
  6. Object side, calculated with the Rayleigh criterion with λ= 520 nm
  7. At max forward current. Tolerance is ± 0.06V on forward voltage measurements.
  8. Used in continuous (not pulsed) mode.
  9. At pulse width <= 10 ms, duty cycle <= 10% condition. Built-in electronics board must be bypassed (see tech info).
  10. Measured from the camera flange of the objective lens to the electronic end of the illuminator. Cable, connector and mount thread excluded.
