Abstract

In some embodiments, an inspection system includes a collimated light source defining a source optical path and useful to cause a collimated light beam to propagate along the source optical path and a sensing device defining a sensor optical path. A positioning device includes a positioning device stage movably disposed relative to the positioning device, sensing device and collimated light source. A retention mount is disposed on the positioning device stage and within the sensor optical path such that when an object is retained within the retention mount, the object blocks at least a portion of the collimated light beam.
