OPTICAL ELEMENT TESTING METHODS AND SYSTEMS EMPLOYING A BROADBAND ANGLE-SELECTIVE FILTER

摘要

An optical element testing system includes a broadband angle-selective filter arranged along an optical path with an optical element to be tested. The system also includes a electromagnetic radiation transducer that outputs a signal in response to electromagnetic radiation that passes through the broadband angle-selective filter. The system also includes a storage device that stores data corresponding to the signal output from the electromagnetic radiation transducer, wherein the data indicates a property of the optical element in response to a test.
