PCCD lenses are designed to enable the 360° side view imaging of small objects. Their innovative optical design, based on a catadioptric system, makes it possible to image small objects, with diameters as small as 7 mm.
The sides of the object are imaged through the catadioptric system, while the top surface is directly imaged onto the center of the detector.
The compactness and high resolution performances are a ideal for the inspection of components like pharmaceutical containers, plastic caps, pre-forms, bottle necks, screws and other threaded objects.
The sides of the object being inspected are observed over a wide view angle, approaching 45° at its maximum; this feature makes it possible to inspect complex object geometries under a convenient perspective.

Sample images taken with catadioptric lenses
Opto Engineering PC CD are pericentric lenses exclusively developed and
produced by Opto Engineering to enable the 360° side view imaging of small
objects. Their innovative optical design, based on a catadioptric system,
makes it possible to image small objects, with diameters as small as 7 mm.
The sides of the object are imaged through the catadioptric system, while the
top surface is directly imaged onto the center of the detector. The
compactness and high resolution performances of these lenses make them the
perfect choice for the inspection of components like pharmaceutical
containers, plastic caps, pre-forms, bottle necks, screws and other threaded
objects.
Opto Engineering PC CD pericentric lenses can work either with 1/2" and 1/3"
detectors, like standard Pericentric Lenses. The sides of the object being
inspected are observed over a wide view angle, approaching 45° at its maximum;
this feature makes it possible to inspect complex object geometries under a
convenient perspective.
The image of the external walls of the object, captured through the
catadioptric system, is inscribed into the short side of the camera detector
within a circular crown. On the other hand, the top of the object is directly
imaged onto the central part of the detector area: both the lateral and top
view of the object are in perfect focus at the same time.
The optics is protected by a glass window, to prevent from the intrusion of
dust and impurities into the optical system. The top of the object is imaged
through a small removable window, located at the center of the lens. This
optical window can be removed and replaced with other type of optics in order
to compensate for the object depth, where necessary.
The window’s mounting thread can also be used to host and fix a LED
illuminator.
