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.
All apertures in the box are provided with vertical channels to hold slit plates and/or colour filters.
The optical accessories included in the set are:
- Acrylic blocks (prisms)- One rectangular, one semi-circular, one triangular prism 60° x 60° x 60°, one triangular prism 90° x 60° x 30°, one triangular prism 90° x 45° x 45°.
- Acrylic Cylindrical Lenses- One double concave, one double convex (both with the same radius of curvature), and one thick double convex.
- Mirrors: One curved metalized plastic (parabolic), one curved metalized plastic (semi-circular), one plane glass (mounted on stand).
- Black slit plate-with three narrow slits at one end and one narrow slit at the other end.
- Another black slit plate with four narrow slits at one end and one wide slit at the other end.
- Set of seven mounted color filters.
It is supplied complete with a spare lamp and working instructions manual
