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.

The invention relates to a method for measuring a light radiation () emitted by a light-emitting diode (). In the method, an end () of an optical fiber () which is connected to a measuring device () is irradiated with the light radiation (), which is emitted by the light-emitting diode (), through an optical device (), so that a portion of the light radiation () is coupled into the optical fiber () and is guided to the measuring device (). The optical device () causes the light radiation () passing through the optical device () to be emitted in diffuse form in the direction of the end () of the optical fiber (). The invention also relates to an apparatus () for measuring a light radiation () emitted by a light-emitting diode ().

Measurement of the light radiation of light-emitting diodes

Device for generating polarized electromagnetic radiation has a diffuser and a polarizer. The diffuser is arranged in a beam path of the electromagnetic radiation. The polarizer is arranged in the beam path of the electromagnetic radiation, to be precise downstream of the diffuser in the direction of propagation of the electromagnetic radiation. The polarizer has a reflective side facing the diffuser, said reflective side being at least partly reflective to the electromagnetic radiation. The polarizer transmits electromagnetic radiation having a predefined polarization and reflects electromagnetic radiation not having the predefined polarization back to the diffuser. The diffuser scatters, in a non-polarization-maintaining manner, at least one portion of the reflected-back electromagnetic radiation not having the predefined polarization.
