Abstract
An exposure device has a bar-like lamp with a filament having luminescent and non-luminescent members connected in alternating series. A filter is disposed in the vicinity of the lamp and is composed of a plurality of filter plates arranged in a longitudinal direction of the filament. Seams between the filter plates are positioned vis-a-vis with the non-luminescent members of the filament of the lamp to reduce disturbances by the seams to the light emerging from lamp.
