摘要：
A video inspection system is provided wherein light from a light source is directed through a field lens. The field lens directs the incident light first in the direction of an object under inspection and then, after reflecting from said object, redirecting the reflected light toward the aperture of an imaging lens/camera assembly. This redirection technique results in magnification of selected regions of the object.
