    Abstract: An optical system comprising an optical instrument and a processing unit. The optical instrument may comprise an illumination source and a sensor. The processing unit may comprise a data storage having stored thereon a characterization of the illumination source and a characterization of the sensor. The processing unit may also comprise a computer configured to calculate a system response of the illumination source and the receiving element considering the characterization of the illumination source and the characterization of the receiving element.

    Abstract: A system to provide radiant energy of selectable spectral characteristic (e.g. a selectable color combination) uses an integrating cavity to combine energy of different wavelengths from different sources. The cavity has a diffusely reflective interior surface and an aperture for allowing emission of combined radiant energy. Sources of radiant energy of different wavelengths, typically different-color LEDs, supply radiant energy into the interior of the integrating cavity. In the examples, the points of entry of the energy into the cavity typically are located so that they are not directly visible through the aperture. The cavity effectively integrates the energy of different wavelengths, so that the combined radiant energy emitted through the aperture includes the radiant energy of the various wavelengths. The apparatus also includes a control circuit coupled to the sources for establishing output intensity of radiant energy of each of the sources. Control of the intensity of emission of the sources sets the amount of each wavelength of energy in the combined output and thus determines a spectral characteristic of the radiant energy output through the aperture.

    Abstract: A spectrophotometer for integration purposes includes a measurement head with an illumination arrangement (10) including at least one light source (11) for the illumination of a measurement object located in a measurement plane (M) under an angle of incidence of at least 45°, with a pick-up arrangement for capturing the measurement light remitted by the measurement object under an angle of reflection of the essentially 0° relative to the perpendicular of the measurement plane, a spectrometer arrangement (30) with an entry slot (31) for the spectral splitting of the measurement light received through the entry slot and captured and with a photoelectric receiver arrangement (32) exposed to the spectrally split measurement light for conversion of the individual spectral portions of the measurement light into corresponding electrical signals. It further includes an electronic control (100), which controls the light source (11) and produces digital measurement values from the electrical signals generated by the photoelectric receiver arrangement. The light source (12) is constructed as a flat cosine radiator and is positioned in such a way that its radiation lobe is essentially perpendicular to the measurement plane (M) and the distance of the light source from the optical axis (21) of the pick-up arrangement (20) is essentially the same as the distance of the light source from the measurement plane. Further provided is a brightness reference arrangement (40) with a redirecting arrangement (44) positionable into and removable from the beam path between the illumination arrangement (10) and the pick-up arrangement (20) and located at a relatively large distance to the measurement plane (M). By the special construction of the brightness reference arrangement (40) and the illumination arrangement (10) as well as special measures for the gloss measurement and measurement value correction, the performance, precision and the application flexibility of the spectrophotometer are significantly improved and expanded.

    Abstract: An LED-based color measurement instrument including an illumination system and a sensing system. The illumination system includes modulated LEDs and a temperature control system for regulating the temperature of the LEDs, thereby improving the consistency of their performance. The sensing system includes a photodiode, a transimpedance amplifier, and an integrator in the first stage to cancel the effect of ambient light on the output of the first stage. The sensing system also includes a lens system for imaging a target area of the target sample onto the photo sensor in a manner so that the product of the target area times the solid angle captured by the lens system is generally uniform over a selected range of distances, thereby reducing the positional sensitivity of the instrument with respect to the target sample.

    Abstract: A color measurement instrument includes a housing and illuminators, a two-dimensional photodetector array, and an optics system within the housing. A UV filter wheel closes the housing to prevent contaminants from entering the housing. The filter wheel supports UV filters and non-UV glass that can be selectively aligned with the illuminators. The photodetectors can be read in parallel, and each photodetector includes a unique spectral filter. The optics system delivers light from the sample target area equally to each of the photodetectors.
