Abstract
An apparatus for sensing microfilms is provided in addition to visible light with a projection lamp for radiating infrared rays which pass through a cold-light mirror to a platform on which a microfilm is disposed. The apparatus is further provided with a projection lens positioned above the microfilm platform. The path of rays is directed from the microfilm platform through the projection lens and then is projected onto an image screen or other sensing surface, for example CCD-device. For adjusting the apparatus for various light spectrum combinations the apparatus is provided with at least one infrared component-reflecting mirror which is displaceable or pivotable to and from the path of illumination rays radiated from the projection lamp.
