Instructions
There is a large (5") achromat lens in a holder whose image can be compared with a similar non-achromat lens, using various apertures that image the light bulb filament. The set up is as shown above. The reduction in chromatic aberration with the achromat is easily shown. See also 6A60.30 - Projection of an Image.
