    摘要: A measurement system for monitoring an LED chip surface roughening process is described. A reflective illuminator can run reflectance measurements. A vertical positioning means can adjust a distance between an objective lens and an industrial sample. A horizontal positioning means can move objects in XY plane, and is specifically configured to hold the industrial sample and a reference sample. An optical sensor can acquire images of the industrial sample. A spectrometer can acquire reflectance spectrums of the industrial sample and the reference sample. A processor can control these components. The processor can perform deskew, and calculate an average reflectance and an oscillation amplitude from the reflectance spectrums of the industrial sample.

    摘要: An angle independent optical surface inspector capable of generating a light beam, directing the light beam to a sample, and de-scanning a reflected light beam that is reflected from the sample, thereby generating a first de-scanned light beam. The de-scanning is performed at approximately one focal length of a de-scanning lens from an irradiation location where the light beam irradiates the sample. The optical inspector also capable of focusing the first de-scanned light beam, thereby generating a focused light beam, and measuring the location of the focused light beam. The measuring of the location is performed at approximately one focal length of a focusing lens from the focusing lens. The incident angle of the light beam is within ten degrees of Brewster's angle. The focusing is performed by an achromatic lens.
