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.

Just one camera

There is no need for multiple cameras placed around and over the object.

Fast image analysis

No image matching software is needed

Single point of view

There are none of perspective effects that some multi-image systems can have. All inspected parts pass unobstructed in the free space below of the lens.
