ABSTRACT:
A light separator (20) for testing the tilt angles of mirror elements (21) of a digital micro-mirror device. The light separator (20) is comprised of two triangular prisms (23, 25). A bottom prism (23) receives light from all mirror elements (21). It transmits light from all mirror elements having a tilt angle over a specified angle (21a, 21b) from a different face than light from mirror elements having a tilt angle less than the specified angle (21c). A top prism (25) receives light from one face of the bottom prism (23). It further divides the light, so that light from all mirror elements having a tilt angle within a specified range (21a) is transmitted from one face and light from other mirror elements (21b) is transmitted from another face.
