Abstract
The author examines different types of illumination apparatus. He discusses their conditions of operation and describes the apparatus devised by himself in greater detail. This apparatus obtains an extremely fine exploring zone simply by projecting the image of a rectilinear incandescent filament on the film by means of a good objective. In order to correct the aberrations rigorously, the light coming from this filament goes through the walls of the lamp in a place where they form parallel faces worked optically. In conclusion, the author describes some comparative tests made on apparatus with a slit and on the rectilinear filament apparatus. The flux emitted by the latter is superior to the flux emitted by the apparatus with the slit, with a consumption approximately one-tenth as great. At the same time the disadvantages of the slits (dust, defective uniformity of illumination, delicacy of centering, etc.) are eliminated.
