This kit is very useful for reflection, refraction and colour mixing experiments. The light box consists of a light source (12V, 24W lamp) producing convergent, divergent, or parallel beam. On one end, an adjustable cylindrical convex lens (for parallel beam) and on the other end, a triple aperture system for colour mixing experiments (lateral aperture are provided with adjustable hinged mirror).
