ABSTRACT:
The microreflectometer system, forming a 0.01 mm.sup.2 area spot, scans a mirror coating for defects of a mirror having a diameter of about 30 centimeters. Tens of thousands of reflectivity measurements are automatically taken as a computer controlled three dimension stage having the test mirror therein is selectively controlled. The reflectivity of each measurement either relative or absolute is used to determine the condition of the coating.
