Abstract

A semiconductor light source configured for a spectrometer may include at least one multipixel chip, at least one color setting component disposed optically downstream of at least one of emission region, and a drive unit. The color setting component may be configured for altering a spectral emission behavior of assigned emission regions. The drive unit may be configured to operate a plurality of mutually independently drivable emission regions successively, such that during operation thereof at least three spectrally narrowband individual spectra are emitted successively by the plurality of mutually independently drivable emission regions together with the associated color setting component from which individual spectra a total spectrum emitted by the semiconductor light source is constituted.
