Hartl Optical Disk
Demonstrate important principles of optics, such as reflection by various shapes of
mirrors, refraction through several types of lenses, total internal reflection and
dispersion. The apparatus consists of a satin finished metallic disc about 30mm in
diameter, graduated around the circumference. On the back of the disc is a handle
that is used to to rotate the disk through 360 degrees in a vertical line about a
horizontal axis perpendicular to the plane and passing through the center of the disc.
The disc is partially shield by a fully-adjustable hood. On the hood, a
circular plate has slits to allow rays of light to pass through and fall on the optical
elements. The hood also has a slot for placing red, green, and blue filters.
The disk face is outlined for various optical elements so that light coming through
the slits strikes them at correct angles. The disk is mounted on a heavy tripod base.
A light sources is needed. Light, optics and filters are not included.
Note: The optical elements are held in place on the metal disk by means of clamping
screws that come with the Accessory set, listed below.
