| titleOfInvention | Increase of usable dynamic range in photometry |
| abstract | The present invention refers to an optical device (100) for determining the presence and/or concentration of analytes in a sample (10), the optical device comprising a detection unit (50) comprising optical path components and a detector (70), said detection unit (50) having wavelength-dependent responsivity, the optical device further comprising a light source (60) for emitting light of different respective usable wavelength ranges, wherein light from the light source is guided through the optical path (51) to the detector (70) to generate baseline signals and response signals relative to said baseline signal indicative of the presence and/or concentration of analytes in a sample (10) being located in the optical path, characterized in that the intensity of the light reaching the detector (70) is being adjusted in a manner reciprocal to the wavelength-dependent responsivity of the detection unit (50) with respect to at least two respective usable wavelength ranges so that a reduction of at least 50 % of the ratio between the maximum baseline signal at one of the selected usable wavelength ranges and the minimum baseline signal at another of the selected usable wavelength ranges is obtained. |
