Abstract: Disclosed herein is a method of calibrating a spectral sensing device. The spectral sensing device includes: a. at least one detector element; b. at least one wavelength-selective element; c. at least one light source: d. at least one sample interface; e. at least one first optical path; and f. at least one second optical path. The method includes: I. illuminating the detector element via the at least one first optical path; II. illuminating the detector element via the at least one second optical path with no sample applied to the sample interface; III. illuminating the detector element via the at least one second optical path with at least one calibration sample applied to the sample interface; 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 herein are a method of determining at least one calibrated optical property of at least one sample, a spectral sensing device and computer programs and computer-readable storage media for performing the methods.

Abstract: The present invention refers to a device (112) for monitoring an emission temperature of at least one radiation emitting element (114), a heating system (110) for heating at the least one radiation emitting element (114) to emit thermal radiation at an emission temperature, a method for monitoring an emission temperature of at least one radiation emitting element (114) and method for heating the at least one radiation emitting element (114) to emit thermal radiation at an emission temperature. Herein, the device (112) for monitoring an emission temperature of at least one radiation emitting element (114) comprises—at least one light source (125), wherein the light source is configured to emit optical radiation at least partially towards the at least one radiation emitting element (114); —at least one radiation sensitive element (126), wherein the at least one radiation sensitive element (126) has at least one sensor region (128), wherein the at least one sensor region (128) comprises at least one photosensitive material selected from at least one photoconductive material, wherein the at least one sensor region (128) is designated for generating at least one sensor signal depending on an intensity of the thermal radiation emitted by the at least one radiation emitting element (114) and received by the sensor region (128) within at least one wavelength range, wherein the sensor region (128) is further designated for generating at least one further sensor signal depending on an intensity of the optical radiation emitted by the at least one light source (125) and received by the sensor region (128) within at least one further wavelength range, wherein the at least one radiation sensitive element (126) is arranged in a manner that the thermal radiation travels through at least one transition material (116) prior to being received by the at least one radiation sensitive element (126), wherein at least one of the at least one light source (125) and the at least one radiation sensitive element (126) is arranged in a manner that the optical radiation travels through the at least one transition material (116) and impinges the at least one radiation emitting element (114) prior to being received by the at least one radiation sensitive element (126); and—at least one evaluation unit (138), wherein the at least one evaluation unit (138) is configured to determine the emission temperature of the at least one radiation emitting element (114) by using values for the intensity of the thermal radiation and the optical radiation.
