Abstract: An optoelectronic image sensor for a color camera comprises an image intensifier which is configured as a proximity-focussed image intensifier diode and contains a photocathode, an interline type semiconductor sensor coupled to the image intensifier where light-sensitive elements are arranged in lines and columns. Between light-sensitive elements of adjacent columns, there are light-insensitive areas. It further comprises a color stripe filter which is disposed in front of the photocathode such that one color stripe of the color stripe filter is associated with one column of light-sensitive elements of the semiconductor sensor.

Abstract: In an image intensifier comprising an evacuated vessel with a first disk which forms an input window and on whose inner surface a photocathode is disposed, and with a second disk which forms an output window and on whose inner surface a fluorescent screen is disposed. The spacing between the first and second disks is small in relation to the diameter of the image intensifier. The input and output windows are plane-parallel, and a spacer ring is disposed between the first and second disks whose inside diameter increases from the area of the first disk in the direction of the second disk. The spacer ring is spaced at its inside diameter as close as possible to the first disk.

Abstract: The invention relates to composite packing films shrinkable by deep drawing and consisting of at least one copolyamide layer containing at least 50% by weight of .epsilon.-caprolactam units and at least one heat-sealable layer, and optionally, an adhesion-promoting layer.
