Abstract
A device (1), such as a detector or imaging device, for detecting ultraviolet light, is described. The device comprises a housing (4) for a chamber. Disposed within the housing is a charge carrier multiplier structure (9) comprising a dielectric sheet (10) having first and second opposite faces (11, 12) and having an array of holes (16) traversing the dielectric sheet between the first and second faces. The device includes a photocathode (13) supported on the first face of the dielectric sheet, having a work function of less than 6 eV. The device includes an anode (14) supported on the second face of the dielectric sheet.
