57AbstractABA method of calibrating a spectral sensing device (110) is disclosed. The spectral sensing de- vice (110) comprises: a. at least one detector element (112) configured for generating at least one detector signal in response to an illumination of the detector element (112) by incident light; b. at least one wavelength-selective element (120) configured for transferring incident light within at least one selected wavelength range onto the detector element (112); c. at least one light source (124) configured for emitting light in at least one optical spectral range; d. at least one sample interface (126) configured for allowing light from the light source (124) to illuminate at least one sample (127) and configured for allowing light from the sample (127) to propagate via the wavelength-selective element (120) to the detector element (112); e. at least one first optical path (128), wherein the first optical path (128) is configured for al- lowing light emitted from the light source (124) to propagate via the wavelength-selective element (120) to the detector element (112) without passing the sample interface (126); f. at least one second optical path (130), wherein the second optical path (130) is configured for allowing light emitted from the light source (124) to propagate via the wavelength-se- lective element (120) to the detector element (112) by passing the sample interface (126) at least once. The method comprises: I. illuminating the detector element (112) via the at least one first optical path (128) to obtain at least one first detector signal; II. illuminating the detector element (112) via the at least one second optical path (130) with no sample applied to the sample interface (126) to obtain at least one open port detector signal; III. illuminating the detector element (112) via the at least one second optical path (130) with at least one calibration sample (156) applied to the sample interface (126) to obtain at least one calibration detector signal; and IV. determining at least one item of calibration information by using the first detector signal, the open port detector signal and the calibration detector signal. Further disclosed is a method of determining at least one calibrated optical property of at least one sample (127), a spectral sensing device (110) and computer programs and computer-read- able storage media for performing the methods.
