Opto Engineering – 360° view [HC SERIES]

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 of various diameters, such as bottles, cans, vials, threaded holes, and tubes.

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 three 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.
• NANO hypercentric lenses (i.e., HCN13xxx models) are designed for the high-quality inspection of the inner surfaces of small cavities, down to 0.75 mm.

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