Abstract
An optical inspection device for measuring the squareness of tube cuts. The optical inspection apparatus includes a tube guide for permitting rotation of the tube whereby its end wall thickness is positioned in the path of a light beam whose output end is magnified and projected on a viewing screen. Variations in the squareness of the tube end may be visually inspected by an operator on the viewing screen.
