Patent ID: 8462328

Claim:
A system for optically inspecting an object, the system comprising: a. a telecentric illumination system having an illumination optical axis and comprising a light source, the light source comprising a bright field illuminating light portion configured to illuminate the object with a bright field illuminating light; and b. a telecentric optical imaging system comprising an imaging sensor and configured to create a bright field image of the object, wherein the telecentric optical imaging system further comprises a lower imaging module having a first optical axis and an upper imaging module having a second optical axis and wherein the illumination optical axis, the first optical axis and the second optical axis are all parallel and are offset with respect to one another in a lateral direction, substantially perpendicular to the illumination optical axis, the first optical axis, and the second optical axis, and wherein light reflected by the object passes through both the lower imaging module and the upper imaging module prior to being incident on the imaging sensor.
