This fundamental item for the study of light phenomena, is composed of a rectangular case containing a lamp with vertical filament (12V – 36W) placed in the upper part. A system of cylindrical converging lenses enables you to obtain converging, diverging or parallel light beams. On the front of the case there are three windows with clasps, whose internal part are mirror-like and endowed with guides for inserting diaphragms and other colour filters. All equipment is contained in a wooden case. Power-unit included.
