A set of optical apparatus for all types of optical experiment involving reflection; refraction and colour mixing. The principal component is a robust light box finished in matt black with a 1W halogen lamp with 0.75m of twin flex. 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. All apertures in the box are provided with vertical channels to hold slit plates and/or colour filters.
