Abstract
A lens housing has an axial bore containing a lens system for projecting through the bore the image of an illuminated object which is located beyond one end of the lens housing. The lens housing is surrounded by a lamp housing which contains a plurality of spaced lamps that are operable to direct spaced, parallel, collimated beams of light through an open end of the lamp housing, and toward the object that is to be illuminated. A paraboiloidal or ellipsoidal reflector, which is interposed between the lamp housing and the object, has in one end thereof a relatively large diameter opening which is releasably secured over the open end of the housing, and has in its opposite end a smaller opening registering with, and for accommodating a portion of the object that is to be illuminated. The collimated light beams are directed by the reflector onto the portion of the object at angles of incidence in the range of 40° to in excess of 90°.
