Description

This is an excellent and economical set for introductory ray optics.  The laser ray box projects one, three, or five parallel bright beams and is equipped with a momentary switch for safety.  A vinyl template with a degree circle and a linear scale forms the optical disk, and the set includes seven clear acrylic optical elements and a mirror with adjustable curvature for investigating refraction, lenses, prisms and mirrors.  The bottoms of the acrylic elements are frosted to show the ray paths inside them.  The set also includes a manual and storage box.
