Abstract
An image intensifier tube and a solid-state image pickup device are combined to form a unified image pickup device. A thin transparent glass layer polished to a thickness of 50 microns or less is interposed between a phosphor layer of the image intensifier tube and a photosensitive layer of the solid-state image pickup device. A microchannel plate may be incorporated to multiply photoelectrons emitted from a photocathode.
