The disclosure relates to a tunable optical light source spanning the UV-range and possible also the visible and near-IR wavelengths. The tunable optical light source includes an input light source, a focusing element, a non-linear crystal arranged to convert the frequency of at least part of the output spectrum of the super continuum source, and a holding unit for the non-linear crystal. The input light source is a super continuum light source with a spectral bandwidth of at least about 300 nm and the holding unit is adjustable for changing the frequency converted output wavelength of the non-linear crystal wsuch that the lowest obtainable output wavelength wof said tunable light source is ultraviolet. The disclosure further relates to an illumination source and an optical measurement system.
