PCPW series

Polyview optics for multiple side views with one shot

Catalog 2019

PCPW optics provide eight different views of the side and top surfaces of an object.

The wide perspective angle (45°) enables the inspection of the side features of an object (for example the threads of a screw or a nut) otherwise impossible to acquire with a single camera.

Both the external walls of an object and its top can be imaged at the same time, while internal surfaces of holed objects can be completely inspected from the outside. A combined view of the internal and external surfaces is possible and an image displaying both the inner walls and the bottom of a cavity can be obtained.

In addition to these unique features, PCPW optics also ensures excellent image resolution and image brightness.

KEY ADVANTAGES

Just one camera
No need for multiple cameras placed around and over the object
Wide viewing angle
45° object sides view makes otherwise hidden features visible
Complete surface inspection
Both inner and outer object surfaces can be imaged in one shot
Very high resolution
Even the tiniest defects can be detected.

Frequently asked questions

Glossary

The diagram shows how Polyview optics image a cylindrical object. The object is observed at a 45° viewing angle, from eight different points of view. Eight different trapezoidal fields of view are obtained: all the object features included in such a trapezoid will be imaged on the corresponding image portion. 45° viewing angle allows for imaging both the sides of a cylindrical object and its top; if the object is a hollow cylinder (hole or cavity), the inner wall of the cavity will be imaged instead of the top, thus enabling both outer and inner sides inspection.

Maximum achievable field of view

In order to perform a complete 360° inspection, each of the eight image portions should image at least 1/6 of the cylindrical surface; this condition ensures a good overlapping between two different lateral views, since part of the object features will be shared by two neighboring image portions..

When the object height is maximum (20 mm) up to 30 mm diameter objects can be inspected

Up to 50 mm diameter objects can be inspected, provided their thickness doesn't exceed 5 mm.

Combined view of both the inner sides and the bottom of a cavity possible up to 30 mm diameter and 10 mm height

LTRN 050 W 45 is a small LED ring illuminator compatible with different OE products and suitable for a variety of inspections. This illuminator is also perfectly suitable for illuminating the inner sides of a cavity imaged by a Polyview lens; the illuminator flange is threaded to fit PCPW series inner mounting interface.
