    The ray box can be used in a single-ray mode without using the plano-convex lens. However, with the lens inserted (plane face towards the light source), and using the two-slit, three slit or broad-slit masks, the emergent light can be made to be divergent, convergent or parallel by adjusting the position of the light source in relation to the lens.

    These facilities enable the ray box to be used in a wide range of optical experiments with transparent flat-based blocks, prisms and mirrors. The colour filters can be used to produce beams of coloured light. However external light levels have to be reduced for maximum effectiveness.
