    • A method of fluorescence measurement on analytes, marked with different fluorescent markers, which have spectrally different fluorescence emissions, in a sample is described, having the following steps: illumination of the sample in the measurement volume using a laser to excite the fluorescence emission of the at least two fluorescent markers, the illumination of the measurement volume being performed with a maximum of one single laser line, having an excitation intensity sufficiently high that the fluorescent markers are jointly excited through 2-photon absorptions, detection of the fluorescence emission using at least two detector devices which are designed for light detection in different spectral ranges in accordance with the spectral fluorescence properties of the fluorescent markers, and performance of a cross-correlation and/or coincidence analysis of detector signals of the detector devices. A measurement device for performing the method is also described.

    • In a calibration reference light source and a sensitivity calibration system using the same, a plurality of single-wavelength light sources for emitting reference lights having mutually different single-wavelengths are used instead of a black body radiation source for radiating a white light, and not only the intensities of the single-wavelength reference lights, but also the wavelengths thereof are measured to obtain sensitivity correction coefficients of intensity-to-radiance conversion data. Thus, obtained reference radiance are highly reliable and sensitivity correction of spectrophotometers and spectral illuminometers can be performed with high accuracy and reliability at a user side, whereby the calibration reference light source and the calibration system using the same can be obtained at low cost.

    • The disclosure generally relates to a method and apparatus for automated spectral calibration of a spectroscopy device. In one embodiment, the disclosure relates to a method for simultaneous calibration and spectral imaging of a sample by: simultaneously illuminating the sample and a calibrant with a plurality of illuminating photons; receiving, at the spectrometer, a first plurality of photons collected from the sample and a second plurality of photons collected from the calibrant; forming a calibrant spectrum from the first plurality of collected photons and a sample spectrum from the second plurality of collected photons; comparing the calibrant spectrum with a reference spectrum of the calibrant to determine a wavelength-shift in the calibrant spectrum; applying the wavelength-shift to the sample spectrum to obtain a calibrated sample spectrum.

    • An optical system has a broadband source and a chirped Bragg grating etalon. In operation, the broadband source provides a broadband optical signal. The chirped Bragg grating etalon responds to the broadband optical signal, for providing a chirped Bragg grating etalon optical signal having a precise set of the optical reference signals. The chirped Bragg grating etalon may include a pair of chirped Bragg gratings. The precise set of the optical reference signals is determined by the spacing of the chirped Bragg gratings of the chirped Bragg grating etalon. The precise set of the optical reference signals includes a series of peaks covering most of a source spectral width of the broad optical source signal with the power at the beginning and end of the spectrum passed unaffected by the chirped Bragg grating etalon due to the limited bandwidth thereof.
