    Abstract: The present invention relates to an optical system having a chamber (26) for receiving an element (E) of body fluid or tissue or environmental sample to be characterized by the optical system, a light source (5) for illuminating the chamber (26) with light, and a spectrometer (6) for recording a spectrum of light originating from the chamber (26), wherein the light source (5) comprising two separate LEDs (5A, 5B) to emit light having at least two spectral maxima of different wavelength ranges, and the light source (5) is coupled to the chamber (26) such that the light is directed from the light source (5) to the chamber (26) when the light source (5) is activated. Further, the present invention relates to a method for determining a parameter with an optical system, wherein the optical system comprises a chamber (26) for receiving an element of body fluid or tissue or environmental sample to be characterized by the optical system, a light source (5) for illuminating the chamber with light, and a spectrometer (6) for measuring a spectrum of light originating from the chamber (26), wherein, in order to determine a parameter representing a property of the element, light having at least two spectral maxima of different wavelength ranges are generated by separate LEDs (5A, 5B) and is directed onto the element, a spectrum comprising reflected components of the light, scattered components of the light, and/or light caused by raman scattering or fluorescence of the element is measured with the spectrometer (6), and the parameter is determined by evaluating the spectrum.

    Abstract: 1. A system (1000), comprising: a radiant source (101) characterized by an average excitation wavelength; a sample (110) disposed to receive radiation from the radiant source, the sample comprising:a first dye;a second dye; and a detector (115) configured to measure emissions from the sample; a first emission spectral element (121a) characterized by a first average emission wavelength; a second emission spectral element (121b) characterized by a second average emission wavelength that is different than the first average emission wavelength; at least one processor (130) comprising at least one memory including instructions to: illuminate the sample with the radiant source and, in response, (1) measure emissions from the sample using the detector and the first emission spectral element and (2) measure emissions from the sample using the detector and the second emission spectral element. A method corresponding to the above system.
