The HC series features hypercentric lenses for sensors up to 1.1” designed for the simultaneous inspection of the inner sides and bottom surfaces of hollow cylindrical samples, such as bottles, cans, vials, containers, pipes and bores.

HC lenses image the inside of cavities from the outside thanks to the special optical path of the rays passing through bottlenecks and narrow openings. This unique optical design allows to fully inspect the inside surfaces of cavities without the need to rotate the sample or use complex multi-camera systems. 
In addition, HC lenses feature variable iris for maximum flexibility and a wide viewing angle to clearly image the features of interest.

HC lenses are available in two different versions:

• SIDE & BOTTOM hypercentric lenses (i.e., HCSIxxx models) are designed for the inspection of both the bottom and the inner walls of cavities in perfect focus;
• BOTTOM hypercentric lenses (i.e., HCBIxxx models) have been developed to specifically inspect the bottom surface of hollow objects at high resolution. By changing the f/N of the lens, part of the side wall can also be inspected in focus.


Hypercentric lenses innovative optical design has been optimized to image inner defects in containers, specifically for the beverage, pharma and cosmetics industries but also to generally inspect hollow objects in many other industry sectors.
