A complete kit providing comprehensive range of optical experiments involving reflection, refraction and colour mixing.
- The kit is designed around a well-ventilated, all-black light box, with a 12V, 24W vertically straight filament lamp
- Connection to a suitable external power source is via a two-core flexible connecting lead terminated in a pair of 4mm banana plugs
- Incorporates an adjustable collimating lens for producing convergent, divergent, or parallel light beams, the other end having a triple aperture system for colour mixing experiments
- Adjustable hinged mirrors along both sides of the box facilitate colour mixing of all three beams
- All apertures in the box are provided with vertical channels to hold slit plates and colour filters
The complete optical set includes:
- Set of 5 acrylic blocks (prisms): one each of rectangular, semi-circular, equilateral triangular – 60 x 60 x 60°, triangular – 90 x 60 x 30° and right angled triangular – 90 x 45 x 45°
- 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 – 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 minimise internal reflections and revealing the path of light as it passes through
- The set is housed in a moulded case for safe storage
Requires a 12V supply (not included) - please see Power Supplies section.
