Abstract: It is object to suppress a fluctuation in an amount of light reflected from a to-be-illuminated surface having a directional property in reflectance characteristics and improve usage efficiency of a bundle of light beams emitted from a light source. In order to achieve the above object, an illumination device that illuminates a to-be-illuminated surface, includes: a surface light source being disposed on a normal line of the to-be-illuminated surface; and a reflection mechanism being provided between the surface light source and the to-be-illuminated surface so as to surround the normal line for reflecting a light emitted from the surface light source toward the to-be-illuminated surface, wherein in the reflection mechanism, a reflection region that reflects the light toward the to-be-illuminated surface and a non-reflection region that does not reflect the light toward the to-be-illuminated surface are alternately disposed along a virtual cylindrical surface surrounding the normal line in a circumferential direction of the virtual cylindrical surface, and three or more reflection regions and three or more non-reflection regions are thereby disposed, each of the three or more reflection regions is a region having a partially-cylindrical shape to follow the virtual cylindrical surface, and the three or more non-reflection regions are dispersedly disposed to surround the normal line in the circumferential direction.

Abstract: The color of light emitted by an assembled light emitting diode (LED) based illumination device with at least two different wavelength converting materials is automatically tuned to within a predefined tolerance of a target color point by modifying portions of the wavelength converting materials. The color of light emitted from the assembled LED based illumination device is measured and a material modification plan is determined based at least in part on the measured color of light and a desired color of light to be emitted. The material modification plan may further include the location of the wavelength converting materials to be modified. The wavelength converting materials are selectively modified in accordance with the material modification plan so that the assembled LED based illumination device emits a second color of light that is within a predetermined tolerance of a target color point.

Abstract: An integrating sphere, and an integrating sphere-based reflectance colorimeter/spectrophotometer for the measurement of color and appearance, having multiple receivers capable of concurrently receiving optical radiation scattered/reflected from a diffusely illuminated sample surface, with the capability of multiple measurement modes (e.g., multiple specular component excluded (SCE), SCE and specular component included (SCI), multiple SCI), multiple areas-of-view for a given measurement mode, multiple viewing angles per measurement mode, and combinations thereof. An embodiment of the invention includes two SCI receivers and two SCE receivers, each disposed at an equal viewing angle relative to the sample surface. For each viewing mode, two sample areas-of-view are provided. The SCE receivers are opposite each other, such that the specular component of each SCE receiver is excluded by the port of the other SCE receiver. The receivers provide the collected light reflected from the sample to a detector which preferably is provided by multiple spectrometers or a single spectrometer having multichannel capability to preferably sense the light from each receiver in parallel.

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 specular-included 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 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.
