An image detector (1) has a first substrate (10) carrying an electromagnetic radiation conversion layer (11) for converting incoming electromagnetic radiation (A) with a first range of wavelengths into outgoing electromagnetic radiation (B) with a second different range of wavelengths and a photodetector array (21) is carried by a second substrate (20) and responsive to the second range of wavelengths for detecting outgoing electromagnetic radiation (B) emitted by the layer (11). The second substrate (20) is mounted to the first substrate (10) by a mounting arrangement (40) defining an insulative space (50) which provides good electrical isolation between the photodetector array (21) and the electromagnetic radiation conversion layer (11). The use of separate substrates (10 and 20) enables the photodetector array (21) and electromagnetic radiation conversion layer (11) to be manufactured independently of one another using optimum processes for producing the desired properties for the photodetector array (21) and electromagnetic radiation conversion layer (11), respectively.
