Abstract

Apparatus for inspecting containers having a sidewall with a shoulder and a heel includes a device for positioning a container for inspection, a light source on one side of the container positioning device, and a camera having a light sensor and an entrance pupil on an opposing side of the container positioning device. A fresnel lens is disposed between the camera and the positioning device. The fresnel lens is positioned with respect to the entrance pupil of the camera so that the light sensor has a field of view that is directed by the fresnel lens through the container sidewall onto the light source at a first converging angle through the shoulder and at a second converging angle through the heel. The positioning device preferably is such that the front surface of the container is positioned adjacent to the fresnel lens, and such that the fresnel lens has a focal point disposed between the front surface and the light source.
