| A complete kit providing comprehensive range of optical experiments involving reflection, refraction and colour mixing. The kit designed around a light box, all black, well ventilated, consisting of a light source 12V, 24W vertically straight filament lamp fitted in the holder through top of the box. Incorporates and adjustable collimating lens towards one end for producing convergent, divergent, or parallel light beam; with other end having triple aperture system for colour mixing experiments. Adjustable hinged mirrors along both sides of the box facilitates colour mixing of all three beams. All apertures in the box are provided with vertical channels to hold slits plates and colour filters. A two core flexible connecting lead terminating in a pair of 4mm banana plugs connects it to low voltage AC power source. The complete optical set includes: Set of 5 Acrylic Blocks (Prisms) one each of rectangular, semi-circular, equilateral triangular - 60°x60°x60°, triangular - 90°x60°x 30° and right angled triangular - 90°x45°x45°. All blocks are free of optical imperfections and sharp edges. Set of 3 Acrylic Cylindrical Lenses one double concave, one double convex (both having same radius of curvature) and one thick double convex. Set of 3 mirrors : highly polished reflecting surfaces and free standing. Includes one each of parabolic, semi-circular and plane glass (mounted on stand) Set of 2 slit plates, black: one with three narrow slits and one narrow, and other with four narrow slits and one wide slit. Set of 8 colour filters, mounted: 3 primary colours - one each of red, blue and green, and 5 secondary colours - one each of cyan, violet, orange, yellow and magenta. Set of 8 Coloured Cards: one each of red, blue, green, violet, orange, cyan yellow and pink. All acrylic blocks and lenses, cylindrical and parabolic mirrors provided with finger grips, enabling their handling without touching their active optical surfaces. The bottoms of all refractive components are frosted to minimize internal reflections and revealing the path of light as it passes through. Supplied complete with a spare bulb with complete set housed in a moulded Styrofoam case for long life storage. |
