Abstract: A system for inspecting bottles includes a conveyor conveying bottles at a first speed. A starwheel, rotating at a second speed, less than the first speed, receives each bottle. Sensors are disposed adjacent the starwheel for detecting at least one of a residual liquid in the bottle and a defect in the bottle. The starwheel deposits each bottle on the conveyor at a downstream position. An outer sidewall inspection system, disposed along the path, has a first camera assembly and a second camera assembly disposed along the path and each bottle passes therebetween. A first belt is disposed along the conveyor in facing relation with a second belt to rotate the bottle. The outer sidewall inspection system has a third camera assembly and a fourth camera assembly disposed along the path, downstream of the first belt; each bottle passing between the third camera assembly and the fourth camera assembly.

Abstract: An apparatus for directing uniform intensity light onto a surface where the light is provided at an acute angle with respect to the surface including a light source that generates initial light rays that are essentially perpendicular to the surface and a guidance member positioned between the source and the surface which receives the initial rays and redirects the rays such that redirected rays are parallel and form acute angles with respect to the surface, the source and guidance member juxtaposed with respect to the surface so that the redirected rays subtend the surface.
