Abstract (en)
[origin: WO2019042748A1] The invention relates to an optoelectronic chip (1) comprising the following elements: a light inlet (11); a wavelength-sensitive optical filter (20); a first photoelectric element (30) for measuring a first light intensity, particularly a first photodiode, the first photoelectric element (30) being arranged such that light (50) penetrating the optoelectronic chip (1) via the light inlet (11), transmittted by the filter, hits the first photoelectric element (30); and a second photoelectric element (40) for measuring a second light intensity, particularly a second photodiode, the second photoelectric element (40) being arranged such that the light (50) penetrating the optoelectronic chip via the light inlet, which is reflected by the filter (20), hits the second photoelectric element (40).
