    Abstract: A densitometer apparatus (410) is disclosed and is adapted to provide color density measurements of object samples. The densitometer apparatus (410) comprises a source light (580) for projecting light toward an object sample comprising a control strip (588, 620). A reflection optics assembly (576) is adapted to measure light density reflected from the object sample when the object sample is in the form of a paper control strip. A transmission optics assembly (618) is adapted to measure transmission density of light rays projected through the object sample when the object sample is in the form of a film control strip. A motor assembly (426) operating with a drive wheel assembly (434) and idler wheel assembly (440) automatically moves the object sample (588, 620) through the apparatus (410) adjacent the source light (580). A pair of guides (468, 470) are selectively adjustable by the operator to control movement of the object sample (588, 620) through the apparatus (410). In response to input from a key switch assembly (492) activatable by the operator, the apparatus (410) is adapted to perform various color density measurement and calibration functions, and display appropriate information to the operator through the use of a visual display (490).

    Abstract: A portable spectrophotometer includes a small-diameter optical sphere (101) as well as optical detectors (130, 136) and signal processing and display circuitry (140, 142) which allows the instrument to be taken to an object to be measured and which provides a readout of color values at the portable instrument. The instrument is capable of providing specular-included and specular-excluded color readings simultaneously. The interior of the integrating sphere is coated with a highly reflective, color-absorbing material, and light from an incandescent lamp (103) is diffused within the sphere prior to reaching the object to be measured. The sphere is provided with a first aperture (120) which receives spectrally-included light and which is positioned to absorb a spectral component of the diffused source light. A second aperture (125) positioned at a corresponding angular position with respect to the object measures specular-excluded light, excluding the specular component absorbed by the first aperture. By appropriately combining the specular-included and specular-excluded light at one wavelength, a value for the specular component is derived.

    Abstract: A light source. The light source may comprise a substrate comprising at least one flexible portion; an illumination source mounted on the flexible portion; and a structural unit positioned relative to the flexible portion to determine a deflection angle of the flexible portion. An illumination angle of the light source may be dependent on the deflection angle of the flexible portion. Instruments including the light source are also disclosed, along with a method of changing the illumination angle of the light source. The method may comprise the steps of removing the structural unit and replacing the structural unit with a second structural unit positioned relative to the flexible portion to deflect the flexible portion by a second deflection angle.

    Abstract: A colorimeter for reading color bars (403, 404) of printed sheets (401) or the like includes a longitudinally extending base (400) including a paper stop (442) along which a sheet to be tested for color may be positioned. An autonomously operating colorimeter head (410) is moved along the base in a direction parallel to the edge of the sheet by means of an electric motor (600) mounted on the base and driving an helical thread lead screw (418) engaging an X-axis carriage supporting the head. The head is moved by operation of the lead screw in a direction parallel to the edge of the sheet, referred to as the direction of the X-axis. The head includes an electric motor and a Y-axis transport supporting an optics unit (510). The optics unit is moved within the head in a direction parallel to a Y-axis, extending perpendicularly to the X-axis.

    Abstract: MULTIANGULAR COLOR MEASURING APPARATUS A spectrophotometer apparatus (200) is adapted to provide spectral reflectance measurements of object, particularly optical characteristics of colored surfaces comprising metallic or pearlescent particles. The apparatus (200) comprises a source light and a reflection optics assembly. Signals representative of reflected light are analyzed and data is generated representative of the spectral response characteristics of the object sample. The apparatus employs a plurality of fiber optic bundles for receiving light reflected from the object sample, with each of the fiber optic bundles being positioned at one of a corresponding plurality of fixed angles different from the angle of illumination by the source light. Reflectance is measured at each angle by sequential switching such that light is impaired from being received from all but one of the plurality of multiple angles. Light received from the fiber optic bundles is transferee to a single array of integral interferencefilter/photodiode devices which modulate the light and determine the spectro characteristics thereof. With the use of fiber optic devices, a single source of illumination and a single optical detector arrangement, the spectrophotometer apparatus is employed within an optimally small packaging configuration, and the apparatus can be maintained in a portable mode while maintaining relatively high accuracy and repeatability.
