• It comprises of a set of optical apparatus for all types of optical experiments involving reflection, refraction and colour mixing.
• The principal component is a robust light box finished in matt black with a 12 V, 24W halogen lamp.
• One end of the box has a cylindrical convex lens in an adjustable sliding mount which allows a parallel, convergent or divergent beam to be produced.
• The other end of the box has a triple aperture system for colour mixing experiments.
• The lateral apertures have adjustable hinged mirrors.
