Abstract: Diffuse reflectance spectroscopy apparatus for use in analyzing a sample comprising a sample receiving location (2) for receiving a sample (3) for analysis; an illumination arrangement (4) for directing light towards a received sample; a detector (6) for detecting light reflected by a received sample; and collection optics (5) for directing light reflected by a received sample towards the detector. The illumination arrangement further comprises an interferometer (42) and a half beam block (45a, 45b) which is disposed substantially at a focus in the optical path for blocking light which exits the interferometer, passes said focus, and is reflected from reentering the interferometer. A half beam block (45a) may be disposed in the optical path between the interferometer and the light source (41) for blocking light that exits the interferometer back towards the light source and is reflected by the light source from re-entering the interferometer and/or a half beam block (45b) may be disposed in the optical path on the opposite side of the interferometer than the light source.

Abstract: In one example, an electronic signal is received from a target color measurement instrument that includes a plurality of color channels. A response of the target color measurement instrument to a light emitted by a target light emitting device is extracted from the signal. The response is calibrated to minimize a difference between the response and an output of a color matching function of a standard observer. Calibrating includes multiplying the response by a calibration matrix. The calibration matrix combines measurements of a first plurality of lights from a tunable light source and measurements of a second plurality of lights from the target light emitting device. A first subset of the measurements of the first plurality and second plurality of lights are made by the target color measurement instrument and a second subset of the measurements of the first plurality and second plurality of lights are made by a reference spectroradiometer.

Abstract: A device may obtain a master calibration set, associated with a master calibration model of a master instrument, that includes spectra, associated with a set of samples, generated by the master instrument. The device may identify a selected set of master calibrants based on the master calibration set. The device may obtain a selected set of target calibrants that includes spectra, associated with the subset of the set of samples, generated by the target instrument. The device may create a transfer set based on the selected set of master calibrants and the selected set of target calibrants. The device may create a target calibration set, corresponding to the master calibration set, based on the transfer set. The device may generate, using an optimization technique associated with the transfer set and a support vector regression modeling technique, a transferred calibration model, for the target instrument, based on the target calibration set.

Abstract: A protective sheath having a closed end and an open end is sized to receive a hand held spectrometer. The spectrometer can be placed in the sheath to calibrate the spectrometer and to measure samples. In a calibration orientation, an optical head of the spectrometer can be oriented toward the closed end of the sheath where a calibration material is located. In a measurement orientation, the optical head of the spectrometer can be oriented toward the open end of the sheath in order to measure a sample. To change the orientation, the spectrometer can be removed from the sheath container and placed in the sheath container with the calibration orientation or the measurement orientation. Accessory container covers can be provided and placed on the open end of the sheath with samples placed therein in order to provide improved measurements.
