Abstract: A curved mirrored surface is used to collect radiation scattered by a sample surface and originating from a normal illumination beam and an oblique illumination beam. The collected radiation is focused to a detector. Scattered radiation originating from the normal and oblique illumination beams may be distinguished by employing radiation at two different wavelengths, by intentionally introducing an offset between the spots illuminated by the two beams or by switching the normal and oblique illumination beams on and off alternately. Beam position error caused by change in sample height may be corrected by detecting specular reflection of an oblique illumination beam and changing the direction of illumination in response thereto. Butterfly-shaped spatial filters may be used in conjunction with curved mirror radiation collectors to restrict detection to certain azimuthal angles.

Abstract: In a detector for spectrometry attached to an integrating sphere, a plurality of detection elements having different spectral sensitivity characteristics is arranged side by side in the same plane on a base, and a side cover is provided such that the detection elements receive light. Thus, the measurement light is directly irradiated to the respective detection elements. Accordingly, the detector for spectrometry has a fast response speed and is excellent in the sensitivity characteristics in a wide wavelength region in the near-infrared area.

Abstract: The apparatus measures the transmission of light in successive falling objects. A beam is projected, wide enough to bathe all the facing surface of the object. An integrating sphere is on the other side of the object and its inlet and outlet apertures provide cut-offs so that only a hollow cone of flux scattered from the object is trapped in the integrating sphere, this flux being measured by a detector. The detector is connected to a micro-processor whose output is a measure of the clarity of the object. When the object is not in the beam, the beam falls on a detector so that the reduction in flux sensed by the detector is a measure of the projected area of the object. The micro-processor divides the signal from the detector by the reduction in flux, thereby making the output substantially independent of the size of the object.
