摘要： A spectrometer apparatus for measuring spectra of a liquid sample, such as a beverage like wine. The apparatus has an integrating cavity with a reflective inner wall to receive a cuvette containing the liquid sample within the integrating cavity. A combination of light inlet ports and light outlet ports are provided to receive light from at least one light source and deliver light to a spectrometer. A light path adjuster is configured to selectively adjust a light path through the integrating cavity so at least two distinct light paths are provided wherein when the light path adjuster is in a first configuration, the apparatus is in transmission mode in which light from the light source follows a first light path; when the light path adjuster 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.
