L21: Geometric Optics

 

Purpose: To demonstrate reflection, refraction, and total internal reflection, and their action in mirrors and lenses.

Description:

 

This is a more modern version of the blackboard optics demonstration in a more easily-used package.

A Ray Optics Demonstration Kit consisting of a source of 5 parallel laser beams; assorted mirrors, lenses and prisms (bottom photo); a collection of background templates that schematically show the components of various optical instruments (eye, camera, telescope, etc.). The light source, templates, and optical components are held magnetically to the mounting board, which can be supported on a stand if desired.

Demonstrate the geometric optics of the various components, using the appropriate templates. The template pictured is for the human eye, which can be used to show ray behavior for a normal eye, and can also show corrections for both near-sightedness and farsightedness. The picture below shows other optical elements available in the kit.

The components can be placed directly on the whiteboards in CHEMP 130.
