    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.

    摘要： A piston-cylinder actuator includes a unique mount for an absolute-position sensor. The mount is made from a bearing material provides a flexible connection between the sensor mount and the cylinder housing. This flexible connection allows the piston rod to deflect naturally, under its own weight or under other laterally-directed forces, while maintaining the distance and perpendicularity between the sensor and the rod surface, within acceptable limits. The sensor mount is made from a bearing material that will allow it to float directly on the rod surface without scuffing or otherwise damaging the rod surface, particularly the markings or other indicia on that surface. Due to the flexible connection between the sensor mount and the cylinder housing, the proper distance between the sensor and the rod surface can be maintained at all times.

    摘要： A sensor includes an enclosure having a housing and a lower cassette that cooperate to provide a sealed volume in which an optical sensor assembly is enclosed and protected. The optical sensor assembly includes a circuit board with a light source and a light detector. The sensor assembly further includes a light pipe that guides light from the sensor onto a target and a lens guides reflected light from the target onto the light detector. Lower ends of the light pipe and the lens are supported by a recess in the lower cassette. Upper ends of the light pipe and the lens are supported by an upper cassette. The upper cassette is positively located and mounted to the circuit board and received in an internal receptacle in the lower cassette. Mounting the lower cassette to the housing encloses the optical sensor assembly in the proper alignment.

    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.
