Purpose: Demonstrate continuous spectrum
Description: The bright point source is used to provide a continuous white light spectrum. Light from the point source is focused by a condenser lens with iris and a 20 cm focal length cylindrical lens onto a slit. A 20 cm focal length convex lens then images the slit onto the screen through an equilateral prism. A lengthy video (144 Megabytes) describing the setup of this apparatus in some detail may be played by clicking here.
