This is for the measurement of wave length of light by reflected system. It consists of a frame 60 x 60 x 50 mm high with a glass plate mounted at an angle of 45° to reflect the light downwards on to a plano-convex lens 50 mm diameter x 100 mm focus, which rests on a plane glass plate placed on the base of the box. Supplied complete with lens.
