PC series

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

Catalog 2019

Addendum 2018

PC pericentric lenses are unique optical systems designed to perform a complete inspection of an object up to 60 mm diameter quickly and reliably: just one camera acquisition is enough to capture the top and lateral faces of an object.

Thanks to this innovative design there is no need to over-complicate the inspection setup with the use of additional mirrors, while delivering the magnification and field depth required to acquire the entire object volume.

The term pericentric comes from the specific path of the light rays: the resulting image shows the lateral views wrapped around the top face, which makes PC series ideal for cylindrical objects, very common in the beverage and pharmaceutical industry.

Classic application examples include bottleneck threads inspection and data matrix reading - the code will always be properly imaged, no matter the facing direction.

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.

Extendend range

Frequently asked questions

Glossary

PC optics are designed to work with 1/3”, 1/2” and 2/3” detectors. The choice of such detectors ensures 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 thin objects can be inspected over a larger diameter.

r(%) = \frac{Side view height (px)}{Detector short side (px)} * 100
