A depolarizing homogenizer including one or more lenslet arrays, for providing a plurality of beamlets associated with different respective parts of a received beam. The depolarizing homogenizer includes a depolarizer comprising different areas which affect polarization differently, the depolarizer being positioned to cause alteration of the polarization characteristics of at least some of the plurality of beamlets. A lens is arranged to at least partially overlap the beamlets having the altered polarization characteristics.

Depolarizing homogenizer

A fluorescence measurement system comprising a broadband light source and acousto-optical tunable filter (AOTF) controlled by a control unit using an acoustic RF signal provided by a Voltage Controlled Oscillator (VCO).

Tunable filter including an angular dispersive element for a broad band source

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.
