    Abstract: A spectroscopic measurement device emits light to a measurement target and measures the measurement light output from the measurement target in accordance with the light emission. A spectroscopic measurement device includes: a first housing having a light shielding property and configured to house a light source that emits light and having a first opening through which the light emitted from the light source passes; a second housing having a light shielding property and having a second opening through which the measurement light passes and configured to house a spectrometer that receives the measurement light that has passed through the second opening; and an arm member configured to relatively rotatably join the first housing and the second housing. A proximal end side of the arm member is rotatably joined with the second housing. The first housing is attached to a distal end side of the arm member.

    Abstract: A spectrometer apparatus (1) is provided for measuring spectra of a liquid sample, such as a beverage such as wine. The apparatus (1) comprises an integrating cavity (3) comprising a reflective inner wall or walls (5), configured to receive a cuvette (7) containing the liquid sample within the integrating cavity (5). A combination of light inlet ports P1, P2 and light outlet ports P3, P4 are provided to receive light from at least one light source (9) and to deliver light to a spectrometer (11). A light path adjuster (13, 13B) is configured to selectively adjust a light path through the integrating cavity (5) such that at least two distinct light paths are provided; wherein when the light path adjuster (13, 13B) is in a first configuration, the apparatus (1) is in a transmission mode in which light from the light source follows a first light path (15) from the or one of the light inlet port(s) to the liquid sample such that the light from the light source irradiates the liquid sample directly before the light transmitted by the sample is transmitted through the or one of the light outlet port(s) and received by the spectrometer (11) for wavelength analysis of the light to provide an extinction spectrum of the liquid sample; and when the light path adjuster (13, 13B) is in a second configuration, the apparatus is in a diffusely reflecting mode in which light from the light source follows a second light path (17) from the or one of the inlet port(s) into the integrating cavity, is incident onto the reflective inner wall or walls of the integrating cavity and is diffusely reflected within the integrating cavity, such that the light from the light source irradiates the liquid sample before being transmitted through the or one of the light outlet port(s) and received by the spectrometer (11) for wavelength analysis of the light to provide an absorbance spectrum of the liquid sample contained in the liquid sample.

    Abstract: A surface refractive index acquisition system for characterization of a sample is provided. The system comprises a grating device configured to receive the sample, and first and second grating regions. First and second grating periods are selected to provide optical resonances for light respectively in first and second wavelength bands. A light source is configured to illuminate part of the first and second grating regions simultaneously. An imaging system is configured to image light from the grating device and comprises an optical element focusing light in a transverse direction and being invariant in an orthogonal transverse direction, the optical element being oriented such that the longitudinal direction of the grating device is oriented to coincide with the invariant direction of the optical element, and an imaging spectrometer comprising an entrance slit having a longitudinal direction oriented to coincide with the invariant direction of the optical element.
