Optics

Accent-Color Wheel Light

Our 9" (23 cm) diameter wheel contains four distinct quadrants, each with violet, indigo, blue, green, yellow, orange and red wedges, in this order. A plastic handle attaches to the center of the wheel, which can be set to spinning with an included cord. At rest, the wheel consists of separate colors. Is this true when it's in motion? Our wheel includes white wedges to increase the light reflected for viewing from across a room. Includes plastic handle, color wheel, cord on spool and Teacher's Guide with sample questions.

$Acrylic Refraction Cube$

Acrylic Refraction Cube

We call it the "disappearing cube" since it appears invisible in sugar water. But it's also perfect for Index of Refraction and Total Internal Refraction experiments. Its 5 cm square faces are made of transparent and highly polished acrylic. The index of refraction is about 1.5. Includes instructions. Also, available with 2.5 cm square faces.

Adventures in Fiber Optics

Not long ago fiber optics was little more than a laboratory curiosity. Physicists and scientists in research labs were the only people doing much work in this field. In the last 20 years all that has changed. From its obscure beginnings in the back of a lab, fiber optics has become an important and rapidly changing technology. It employs many of the world's brightest scientists and business people.

The kit is suggested for ages 10 and above. It contains materials and an instruction manual to complete five unique projects and 20 exciting experiments such as:

* Bending a Light Guide
* Fluorescence
* Tyndalls's Prestigious Experiment
* Special Fiber Optic Lighting
* Art of Polishing Glass
* Making Your Own Image Conduit
* Creating a Holiday Ornament

Kit items include penlight, rubber light hood, 6 different optical fiber types, ulexite fiber optic rock, 3 coherent fiber optic components, color filters, lens, star/constellation map, polishing film and other miscellaneous components.
