    Abstract: A common aperture, multi-mode optical imager for imaging electromagnetic radiation bands from a field of two or more different wavelengths is described. Fore-optics are provided to gather and direct electromagnetic radiation bands forming an image into an aperture of the multi-mode optical imager. The image is divided into two different wavelength bands, such as visible light and long-wave infrared. The first wavelength band (e.g., visible light) is detected by a first detector, such as a CCD array, for imaging thereof. The second wavelength band (e.g., long-wave infrared) is detected by a second detector, such as an uncooled microbolometer array, for imaging thereof. Additional optics may be provided for conditioning of the first and second wavelength bands, such as such as for changing the magnification, providing cold shielding, filtering, and/or further spectral separation.

    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.
