  • Method for testing curved reflective surfaces
    Patent number: 11079326
    Abstract: Methods and systems for calculating a reflectance value of a reflective coating on a curved surface of an optical element include calculating the reflectance value by taking a series of photon count measurements of an extended radiation source over a range of values of emitted radiation reflected from the curved surface into a detector. A combination of the measurements and a known value of accepted or conforming reflectance for the reflective coating is used to calculate the reflectance value of the reflective coating on the curved surface.
