ABSTRACT OF THE DISCLOSURE Apparatus for duplicating microfiche, which is of moderate cost yet which operates rapidly to make duplicates of high quality from both jacketed and unjacketed microfiche. A relatively uniform and collimated light source is provided for use with jacketed microfiche, by utilizing a bank of fluores- cent aperture lamps and a bank of cylindrical lenses between the lamps and microfiche, with the side of the lenses closest to the microfiche being flattened and with the lenses having baffles of lower index of refraction than the clear segments of the lenses. A developing station for holding gaseous ammonia or other developing medium is sealed by an inflatable seal. -1-
