Inner inspection

Key advantages

  • Inspection of cavities from inside
    Hidden internal features and defects are clearly viewed
  • High resolution
    The catadioptric design enables the detection of tiny defects over a very wide angle of view
  • Flaw detection
    Coarse deformations revealed using direct illumination
  • Surface defect enhancement
    Mixing direct and indirect illumination makes it possible to emphasize tiny and scarcely visible defects.
  • Small diameter inspection
    Now down to 5.5 mm
  • New integration with Optotune liquid lens technology
    PCBP-AF boroscopic probes allow for an extremely fast and repeatable change in focus

Notes

  1. Working f-number (wf/N): the real f-number of a lens in operating conditions.
  2. Tolerance ± 2%
  3. Used in continuous (non-pulsed) mode.
  4. Constant voltage power supply
  5. Constant current power supply
  6. Measured from the front end of the mechanics to the camera flange.

Additional notes

  1. Recommended use of a 1/2" sensor as the image may be decentered

PCBPN for inspection of holes with diameters between 5.5 and 25 mm

Inspection area

Boroscopic probes with liquid lens technology

PCBPN for inspection of holes with diameters between 5.5 and 25 mm

An integrated LED source (for PCBP0xx and PCBPN013-WG) illuminates the cavity both diffusely and directly. The diagram on the left shows the different illumination areas. Diffused illumination is used for defect detection and component inspection.

Direct/specular illumination can be efficiently used to check for surface deformation on metal and highly reflective objects as well as to measure the hole diameter.

The image of the cavity covers around 50% of the detector height: the continuous red line indicates the bottom view of the cavity, the dashed line shows the upper view while the dash-dotted line refers to the undercut view on the cavity.

Unwrapped image. 360LIB-01 dedicated software library is available to easily and accurately unwrap the images.

Boroscopic probes with liquid lens technology

The new PCBPxxx-AF models feature an integrated liquid lens for fast and accurate focusing of different diameters. Optimized for sensors up to 2/3", these lenses further enhance the extreme versatility of the probes.

The refocus (automatic or manual) in PCBP probes is used to compensate for any inaccuracies in positioning inside the sample which is very often done by a robotic arm. These inaccuracies may be due to:

  • positioning (centering) by the robotic arm itself;
  • samples of different sizes and with features to be focused one at a time.

These samples may require checks such as the presence/absence of defects within a groove (can be dirt, threads, burrs), or data matrix reading.

PCBPxxx-AF optics with integrated liquid lenses allow you to change focus quickly and accurately.
