    Abstract: An apparatus for measuring light properties includes a housing defining a light input port; as well as a first light detector; a second light detector; and a coupling element. The first light detector is a single channel light detector or a multiple channel light detector. The second light detector is a multiple channel light detector. The coupling element is configured and arranged to selectively couple light incident from the light input port to one of the first light detector and the second light detector. As an alternative, a beam splitting element can be used instead of the coupling element. The beam splitting element receives light from the light input port and then splits the light and delivers a portion of the light to the first light detector and a portion of the light to the second light detector.

    Abstract: In a wavelength calibration method, an observed spectrum of a light that has a wavelength band is obtained, wherein the light has at least an attenuated wavelength component that corresponds to at least a predetermined absorption wavelength that is included in the wavelength band. A corrected spectrum is then obtained from the observed spectrum, wherein the corrected spectrum has reduced dependencies upon the full width at half maximum of an emission band of the light and upon an intensity ripple period of the light.

    Abstract: Disclosed are photometric methods and devices for determining optical pathlength of liquid samples containing analytes dissolved or suspended in a solvent. The methods and devices rely on determining a relationship between the light absorption properties of the solvent and the optical pathlength of liquid samples containing the solvent. This relationship is used to establish the optical pathlength for samples containing an unknown concentration of analyte but having similar solvent composition. Further disclosed are methods and devices for determining the concentration of analyte in such samples where both the optical pathlength and the concentration of analyte are unknown. The methods and devices rely on separately determining, at different wavelengths of light, light absorption by the solvent and light absorption by the analyte. Light absorption by the analyte, together with the optical pathlength so determined, is used to calculate the concentration of the analyte. Devices for carrying out the methods particularly advantageously include vertical-beam photometers containing samples disposed within the wells of multi-assay plates, wherein the photometer is able to monitor light absorption of each sample at multiple wavelengths, including in the visible or UV-visible region of the spectrum, as well as in the near-infrared region of the electromagnetic spectrum. Novel photometer devices are described which automatically determine the concentration of analytes in such multi-assay plates directly without employing a standard curve.

    Abstract: Time-divisionally-multiplexed light receiving signals are sampled at a predetermined time interval as they are, and then converted into digital data. Then, address is determined based on an index signal as a standard of the time-divisional multiplexing, and the data are sequentially stored in a data memory. When the data are sequentially read out, change of quantity of the data is obtained to determine a period having the smallest change in quantity as an effective period. Then, the data included in the effective period are selected and separated to a sample side beam, reference side beam and cutoff period. Thus, the multiplexed light receiving signals are accurately separated by the digital data.
