Title:
SEMICONDUCTOR LIGHT SOURCE, OPERATING METHOD AND SPECTROMETER
Document Type and Number:
WIPO Patent Application WO/2019/072867
Kind Code:
A3
Abstract:
In one embodiment, the invention relates to a semiconductor light source (1) for a spectrometer (10) and comprises a multi-pixel chip (2) having a plurality of emission regions (20) which can be controlled independently of one another. A colour adjustment means (31, 32) is arranged optically downstream of the emission regions (20) or is integrated in the emission regions (20) and is set up to change a spectral emission behaviour of the associated emission regions (20). A control unit (4) is set up to operate the emission regions (20) one after the other such that a plurality of spectrally narrow-band individual spectra (E), from which a total spectrum (G) emitted by the semiconductor light source (1) is regrouped, are emitted by the emission regions (20) one after the other together with the associated color setting agent (31, 32) during operation.
