Supplied in a beautiful plywood box with prism holder and grating holder
Made from specially designed rugged aluminium extrusion and also permits the use of standard Light Box and Optical set for ray optics investigations. The accompanied prism table provides for the experiments in diffraticon of light through prisms. The Light Box can itself be used as light source and the lens and blocks (prisms) in the opcal set on the prism table. The extruded optical bench length has a 0-150cm Ã?? 1mm scale and has lt-proof, easy sliding moulded plastic riders with index mark for mounting of various uprights and accessories. The opcal Bench comes complete with following components
1)-Â 1.5m long straight anodized aluminium extrusion opcal bench with scale -?? 1 No.
2)-Â -Â Special mounting plaorm with metal upright to support Light Box -?? 1 No.
For exploring the various concepts of optics involving reflection and refraction using ray tracing technique. Comprises a sheet metal disc, about 30cm in diameter, painted white at the top with clamping assembly at its underside for mounting it on a vertical support rod in either of horizontal or veritcal plane and is rotatable about its axis. The upper side of disc has a circular scale along its rim graduated 90-0-900-90 and divides the disc in four equal quadrants with its center clearly marked. Shapes of various opcal elements also clearly marked on the disc to facilitate their placement while performing experiments. The clamp at the underside has metal bar projecting radially outside with adjustable lamp holder mounted at the other end with an adjustable collimating lens to get divergent, convergent or parallel beam as required. A rotatable disc attached in front of collimating lens provides option of single, double, triple or quadruple slits for range of experiments. Complete assembly mounted on stable cast metal heavy base. Supplied complete with reflecitve components one each of plane glass mirror, polished semi-circular cylindrical mirror; and set of 6 refracitve components, acrylic blocks (prisms) one each of semi-circular, bi-convex, bi-concave, right angled prism, equilateral prism and trapezoidal prism. All opitcal elements provided with powerful magnets at their boom for placing them securely on the disc in either of horizontal or vertical disc posiiton. The booms of all refractive components are frosted to minimize internal reflections and revealing the path of light as it passes through.
LO-6268Â Hartle's Optical Disc, Rotatable
