Pericentric lenses

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 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.

Pericentric Lenses are an exclusive product developed by Opto Engineering to enable 3D peripheral vision of objects without the aid of mirrors. By means of this unique optical design, just one camera shot is enough to capture the top and side views of an object.

The name "pericentric" is because of the specific path of the light rays: the aperture pupil is seen from object space as if it was moving around the peripheral zone of the front optical group.

Pericentric imaging

Pericentric lenses are designed to work with 1/2" and 1/3" detectors. The choice of such detectors grants the most appropriate optical magnification factor to achieve the field depth required by high resolution 3D pericentric imaging.

The image of the front surface 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.
