PC series

Pericentric lenses for 360° top and lateral view with just one camera

Tech info

PC pericentric lenses are unique optics designed to perform complete inspection of objects up to 60 mm in diameter, quickly and reliably.

The innovative design allows one camera to see the top and lateral surfaces of an object in perfect focus all in one image. This allows you to greatly simplify the layout of the vision system, with no need for multiple cameras, lenses or mirrors.

The term pericentric comes from the specific path of the light rays: the lateral surface of the object appears to be wrapped around the top face, making the PC series ideal for cylindrical objects which are very common in the beverage and pharmaceutical industry.

Typical applications include bottleneck thread inspection, and data matrix reading - the code will always be properly imaged regardless of its position.

KEY ADVANTAGES

  • Just one camera
    No need for multiple cameras placed around and over the object.
  • Fast image analysis
    No image matching software is needed as the picture is not segmented.
  • Single point of view
    No perspective effects typical of multi-image systems.
  • Smooth on-line integration
    Inspected parts pass unobstructed in the free space below the lens.

Glossary

PC optics are designed to work with 1/3”, 1/2” and 2/3” detectors. These detectors ensure the most appropriate optical magnification factor to achieve the field depth required by high resolution 3D pericentric imaging.


The image of the top of the object and its sides are inscribed into the short side of the camera detector.

The smaller the object diameter, the larger the object height which can be inspected, while short objects can be inspected over a larger diameter.


The tables below show possible combinations of object diameters and heights along with the appropriate working distance and recommended F-number; the “r” parameter for each configuration is also listed.

The “r” parameter is the ratio between the side view height (the circular crown thickness) and the detector short side. It provides information about side view resolution. The higher the “r” value, the higher the resolution that can be achieved in the side view.

PC working distance r(%)= Side view height (px) Detector short side (px) * 100 unwrapped image sample
