Abstract: A system for measuring the color quality of rounded objects is disclosed. A stand (18) has a mandrel (24) for holding the object in a fixed position. Preferably, the mandrel (24) includes an expandable bladder (38) mounted for rotation on an axle (40). The stand (18) has a reflectometer (10) coupled thereto in such a way as to permit angular movement of the reflectometer (10) in a fixed plane. The can is clamped in a fixed position between the mandrel (24) and the reflectometer (10) such that the densitometer is in a fixed radial orientation relative to the surface of the object. Different points on the surface of the object may be measured by rotating and translating the object and/or the reflectometer (10). Rotational and translation control of positioning can be performed automatically.

Abstract: Structural improvements to photometric apparatus (colorimeter, spectral photometer) used to measure parameters determining the color (reflection luminants, three chromatic components, etc....). There is proposed a new optical geometry which could be defined as spherical-diffused (illumination)/spherical-diffused (observation). There are two main embodiments, the first in association with an existing photometric apparatus, the new optical geometry being coupled outside said apparatus, and the second one consisting to integrate the new optical geometry in the measuring apparatus. In both cases, the structures which present the new optical geometry are also used as sample holders.

Abstract: Described herein are methods and apparatus for spectroscopic analysis of samples. In many embodiments, an apparatus for providing spectroscopic analysis of a sample comprises a sample holder. For example, the sample holder may comprise a consumable single use sample holder that can be readily coupled to and removed from a measurement apparatus such as a spectrometer. The sample holder may comprise a measurement surface configured to receive the sample during measurement, wherein the measurement surface may comprise a porous mesh. The porous mesh can receive the sample to optimally configure the sample for spectroscopic measurement, as described in further detail herein.

Abstract: The present application describes a NIR spectrometer for label-free, rapid, portable and high-precision molecular composition analysis of a sample. The NIR spectrometer is integrated in a lab-on-chip and comprises a broadband NIR source configured to generate NIR light pulses; collimating and focusing objectives; a PDMS chamber mounted on a silicate glass support and designed to be filled with the sample and to receive an NIR light beam from a channel waveguide; the cannel waveguide built in a silicate glass support and configured to transmit the NIR light beam through the sample; an optical spectrum analyser configured to receive the NIR light beam, partially absorbed by the sample, and to measure an output signal intensity of the light beam versus a wavelength of said light beam; optical fibres connecting the components of the NIR spectrometer; and a computing unit.

Abstract: Aspects of blending data detected by a monochromator over multiple wavelength ranges is described herein. In one embodiment, the monochromator includes a diffraction grating, a grating drive motor that rotates the diffraction grating to provide, by diffraction of broadband light, first dispersed wavelengths of light and second dispersed wavelengths of light, a detector that detects a first reflection from the first dispersed wavelengths of light and a second reflection from the second dispersed wavelengths of light, and processing circuitry that blends data values from the first reflection and data values from the second reflection together to provide a spectrum of combined data values. By blending data detected over multiple ranges, measurements of relatively high precision and quality can be provided over a wider spectral range.
