Abstract

According to an example aspect of the present invention, there is provided a hyperspectral light source system, comprising a broadband light source arranged to generate and radiate a broadband light signal, a rotating multi bandpass filter arranged to pass through a part of the broadband light signal on one of multiple passbands of the hyperspectral light source system, wherein a rotation angle of the rotating multi bandpass filter determines the part of the broadband light signal that passes through the rotating multi bandpass filter and a tunable filter adjusted to pass through the part of the broadband light signal, coming from the rotating multi bandpass filter, on said one passband of the hyperspectral light source system.
