    Abstract: In a color measuring instrument, an integrating sphere is used to illuminate the sample and fiber optics are used to carry light diffusely reflected from the sample and from an interior wall of the sphere to a spectrometer. The transmitting ends of the fiber optic bundles are fixed in the housing of the spectrometer as entrance slits for the spectrometer, which includes a fixed grating and one or two arrays of photodetectors to detect the spectra dispersed by the grating from light received from the two transmitting ends.

    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.

    Abstract: A readhead with reduced height sensitivity for use in a reflectance photometer that measures reflectance of diffuse light from a sample disposed outside the readhead includes a housing with an upper spherical portion and a lower conical portion. The inner peripheral surface of the upper portion is hemispherically configured and the inner peripheral surface of the lower portion is conically configured to permit illumination of a sample disposed outside the readhead. The angle of the cone defined in the conical portion of the housing is in the range of 45.degree.-60.degree.. The inner peripheral surfaces of the upper and lower portions are coated with a highly reflective material, such as barium sulfate. The apex of the conically configured housing portion is truncated to provide a light transmitting aperture for sample illumination. A sample is positioned adjacent the light-transmitting aperture below and outside the conically shaped readhead housing portion. The housing includes a second aperture for receiving a high intensity light from a flash lamp or incandescent light to illuminate the interior of the housing and diffusely illuminate the sample. A baffle is located adjacent the second aperture to avoid direct illumination of the sample. Fiberoptic bundles and photodetectors as well as lenses and reflecting surfaces are provided to detect the amount of diffuse light reflected from the sample.

    Abstract: Apparatus and method for biological fluid analysis involving radiation measurement. The apparatus includes a pipetting dispenser having means for directing radiation from the piston thereof generally axially through the liquid in the pipette tube such that the pipetting dispenser serves not only as a means for measuring and mixing liquids, but also serves as a cuvette. The apparatus and method provide maximum radiation path length to accommodate liquids of different optical density. Still another feature of the apparatus and method is the provision of means for removing liquid from the outer surface of a pipette tube, which means are readily adapted to automated procedures. The apparatus in one embodiment is adapted for absorbance measurement of analyte samples, and in another embodiment is adapted for measurement of fluorescent radiation from analyte samples.

    Abstract: A radiation dispersing cavity has its interior surface covered by a plurality of deformations, each of which acts as a dispersing element which is small with respect to the effective diameter of the cavity and yet large with respect to the wavelengths processed by the integrating cavity. The interior surface of the cavity is coated with a material which provides the proper reflectivity for the wavelengths of interest.
