Abstract
There is disclosed a filter for a vehicle window comprising a layer of filter material, the layer of filter material being for substantially preventing the transmission of radiation at a first predetermined visible wavelength band, the first predetermined visible wavelength band covering the wavelength of a predetermined laser threat, whilst substantially allowing visible wavelengths outside of the band to be transmitted, such that the filter can offer a visible light transmission of at least 70%, and a radiation detector, such that radiation at the first predetermined wavelength band can be detected.
