Optics

Catalogue No: 1110840/2

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 with provision for mounting it on a vertical support rod in either of horizontal or vertical plane and is rotatable about its axis. It has a circular scale graduated 90-0-90-0-90 x 1 degree and divides the disc in four equal quadrants with its center clearly marked. Shapes of various optical elements also clearly marked on the disc to facilitate their placement while performing experiments. It also has provision for mounting adjustable lamp holder 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 reflective components : one each of plane glass mirror, polished semi-circular cylindrical mirror; and set of 6 refractive components of acrylic : one each of semicircular, bi-convex, bi-concave, right angled prism, equilateral prism and trapezoidal prism. All optical elements provided with strong magnets at their bottom for locating them on the disc in either of horizontal or vertical disc position. The bottoms of all refractive components are frosted to minimize internal reflections and revealing the path of light as it passes through.
* Set of 6 Optical elements, one each of semi-circular, bi-convex, bi-concave, right angled prism, equilateral prism and trapezoidal prism, packed in a case for use with Hartle’s Optical Disc
