Abstract: An imaging section that detects the amount of light separated by a wavelength tunable interference filter to acquire a spectroscopic image (imaging device and light amount acquisition section) detects the amount of light successively separated for three wavelengths to acquire spectroscopic images for producing a combined image. A display controller causes a display section to display a combined image based on the spectroscopic images for producing the combined image. A specified position detection section identifies based on user's operation a specified position where a colorimetry result is to be outputted. The imaging section detects the amount of light successively separated for a plurality of wavelengths by the wavelength tunable interference filter to acquire spectroscopic images for colorimetry corresponding to the plurality of wavelengths. A colorimetry section measures the color in the specified position by using the amount of light obtained from each of the spectroscopic images for colorimetry.

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.

Abstract: Modular systems can be used for optical analysis, including in-situ analysis, of stimulated liquids. An excitation module can include a radiation sources, e.g., a laser, LED, lamp, etc. A detection module can include one or more detectors configured to receive spectral and/or temporal information from a stimulated liquid. Such systems can be used to identify or measure optical emissions including fluorescence or scattering. The efficient excitation of liquid samples and collection of emissions from the samples provides substantial, up to four-fold increase in the emission signal over prior systems. In an example, emission measurements can be conducted in an isolated sample compartment, such as using interchangeable modules for discrete sampling, flow-through sampling, or sampling via fiber probe. The systems and methods described herein can be used to characterize natural aquatic environments, including assessments of phytoplankton pigments, biomass, structure, physiology, organic matter, and oil pollution.
