Abstract
An electromagnetic filtering system comprising an electromagnetic radiation source, a filter chamber to filter the radiation and a filter chamber control system to selectively modify the contents of the filter chamber in order to modify the wavelengths of the radiation that pass through the filter chamber. There is also provided a method of controlling an electromagnetic filtering system that comprises a controllable filter chamber capable of being controlled so as to selectively be filled with a filter material, the method comprising —determining filtering characteristics to be provided by the filtering system, —determining whether the filter chamber should be filled with the filter material, and —controlling the filter chamber to be filled as determined.
