description | Disclosed is an illumination system for a metrology apparatus and a metrology apparatus comprising such an illumination system. The illumination system comprises an illumination source; and a linear variable filter arrangement configured to filter a radiation beam from said illumination source and comprising one or more linear variable filters. The illumination system is operable to enable selective control of a wavelength characteristic of the radiation beam subsequent to it being filtered by the linear variable filter arrangement. |
