Product Description

Hartle’s Optical Disc

A useful tool for the study and demonstration of fundamentals of geometrical optics.  Comprises of a circular metal disc with circular scale from 0° to 90° graduated in degrees, printed around the edge of the disc and divides the disc in four quadrants of a circle. The disc can be mounted both vertically as well as horizontally on the stand. A 12V 24W light source with a connecting lead has a special filament with adjustable collimating lens and circular disc with slits to provide output of varying widths, type and number of beams. Different shapes of accessories of optics set are printed on the disc surface, which acts as guides for placing the accessories accurately for ease in experiment and better results. Each optical accessory has grounded bottom for clear view of passing rays and small magnets embedded at its bottom to hold it firmly to the disc in the desired position.
