Abstract: A color measurement instrument that is capable of both spot reading and strip reading. The instrument includes a handheld unit and a docking unit. When removed from the docking unit, the handheld unit is used for spot reading. When docked in the docking unit, the handheld unit and the docking unit are used together for strip reading. The handheld unit includes a self-storing target that is deployed for spot reading and stored for ship reading. The handheld unit also includes a self-storing calibration plaque that is deployed for calibration and stored otherwise. When docked, the handheld unit teeters on the docking unit between a normally closed position and a manually selectable open position to accommodate a variety of sample thickness.

Abstract: A portable spectrophotometer (100) includes a rotating wheel (214) provided with a plurality of filter characteristics in the 400 to 700 nanometer wavelength range and operated at a constant speed. The filters are moved between an optical conduit (210) and a photoelectric sensor (220) as the wheel is rotated. Light reflected from the object sample is conducted through the optical conduit (210) and focused on the optical sensor (220) by means of a focusing lens (252). A side sensor (222) receives light from one of the three lamps (206) through the filters as the wheel is rotated and provides output signals which are used as reference signals for the individual filters. An integrating sphere (512) with an aperture (541) for conducting specularincluded light reflected from the object and an aperture (543) for conducting specular-excluded light from the object is incorporated with a rotatable filter wheel (520), with a plurality of filters having filter characteristics in the 400-700 nanometers wavelength range.

Abstract: A portable spectrophotometer includes a rotating wheel provided with a plurality of filters having filter characteristics in the 400 to 700 nanometer wavelength range. The filters are moved between an optical conduit and a photoelectric sensor as the wheel is rotated. In one embodiment, a lamp housing contains three object illuminating lamps circumferentially spaced apart by 120 DEG and projecting light onto the object sample at a 45 DEG angle to the object sample. Light reflected from the object sample is conducted through the optical conduit and focused on the optical sensor by means of a focusing lens. A blocking filter is interposed between the lens and the wheel and serves to block light outside of the 400 to 700 nanometer wavelength range. A side sensor receives light from one of the three lamps through the filters as the wheel is rotated and provides output signals which are used as reference signals for the individual filters. In another embodiment, the spectrophotometer includes an integrating sphere with an aperture for conducting specular-included light reflected from the object and an aperture for conducting specular-excluded light from the object. The integrating sphere spectrophotometer also includes a rotatable filter wheel, with a plurality of filters having filter characteristics in the 400 to 700 nanometers wave length range. A side sensor is also provided with the integrating sphere spectrophotometer. As the wheel is rotated, specular-included and specular-excluded light from an object sample to be tested is projected simultaneously through apertures of the sphere. Light detected by a side sensor is also simultaneously detected through one of the filters of the filter wheel. The integrating sphere spectrophotometer also includes an arrangement for providing calibration and compensation of reflectance measurements.

Abstract: A portable colorimeter housing (100) has an upper portion (103) which is mounted on a lower portion (101) in a cantilever fashion and is adapted to receive sheets larger than the device for purposes of obtaining tri-stimulus color measurements. An adjustable paper guide (119) determines the distance that a sheet is inserted between upper (163) and lower (161) plates. A sheet to be measured inserted in the opening (109) will operate a micro switch (139) which activates a motor operative to advance the sheet between a motor driven drive wheel (135) in the lower plate (161) and an idler roller in the upper plate (171). Transmittance or reflectance measurements are taken by means of photodetector cells (242) including colorimetric filters. A user programmable processor performs pattern recognition and control functions.

Abstract: The specification discloses a portable spectrophotometer (10) providing improved movement and control of the sample (S) during analysis. The unit (10) includes a base (12) and an upper assembly (14) supported on the base (12) for floating movement. Both a spectral measurement engine (20) and drive rollers {104) are contained within the upper assembly. The base ( 12) includes independently suspended idler ropers (16), and the drive rollers (104) engage the idler wheels (16), so that at least a portion of the weight of the upper assembly (14) is borne by the engaging drive rollers (104) and idler rollers (16). The upper assembly (14) therefore floats up and down with samples (S) of varying thickness moving between the rollers (104 and 16). Additional upstream idler rollers (18 and 24) on the base and the upper assembly engage one another and bear a portion of the weight of the upper assembly (14) to create tension in opposition to the drive rollers (104) to hold the sample (S) taut. A planar media guide (130) is located on the underside of the upper assembly (14) and surrounds the spectral engine (20) to engage the sample (S) and reduce flexing and bowing of the sample (S). A manually actuated backer (30) is supported by the base (12) to selectively present to the spectral engine (20) one of two areas (52a and 52b) with different reflective properties. The unit (10) may include a first light source (21) in the spectral engine and a second light source (60) in the backer (30) so that the spectrophotometer (10) is capable of both reflective and transmissive analysis.

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.

An adjustable paper guide determines the distance that a sheet is inserted between upper and lower plates. A sheet to be measured inserted in the opening will operate a micro switch which activates a motor operative to advance the sheet between a motor-driven drive wheel in the lower plate and an idler roller in the upper plate. Transmittance or reflectance measurements are taken by means of photodetector cells including colorimetric filters. A user programmable processor performs pattern recognition and control functions. An optical housing assembly mounted on the upper plate includes a substantially cylindrical body provided with a horizontally extending channel and a mounting bar disposed in the channel is insulated from the cylindrical housing by air space except in peripheral areas of the cylindrical portion, thereby conducting heat generated by the high intensity light source to an area away from heat sensitive filters.
