Since it is labeled in electron volts and nanometers, you can use it in both your physics and chemistry labs. It is plastic and contains a built-in chart of common spectral lines. 31 x 18 cm long. With instructions. See Enlarge Click to Enlarge Filter Sheet Set, 10 Colors Place these unmounted 10 x 10 cm sheets on a meter stick optical bench. Pack of 10 colors. See Enlarge Click to Enlarge 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. See Enlarge Click to Enlarge Prism, Equilateral, Acrylic Experiment with diffraction, dispersion, and spectrum formations with these highly polished acrylic prisms. Sizes are as follows: 20 x 50 mm 25 x 75 mm 25 x 100 mm See Enlarge Click to Enlarge Lens, Glass 38mm Set/6 These are great for optical benches, and other experiments in optics and come with a variety of useful focal lengths. One each: double convex, planoconvex, concavo-convex, double concave, plano-concave and convexo-concave. 6 demonstration glass lenses 38 mm in diameter and focal length of 20, 30 and 40. See Enlarge Click to Enlarge 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. See Enlarge Click to Enlarge Prism, Equilateral, Glass Our highly polished glass prisms are ideal for dispersion of white light into its spectrum colors, refraction of light studies, and prism spectrometer principles. Sizes as follows: 27 x 50 mm 25 x 75 mm 25 x 100 mm See Enlarge Click to Enlarge Mirror, Concave & Convex Our extensive selection of spherical mirrors can be used for many experiments in the optics lab. Unmounted, of optically true silvered glass with scratch-proof copper backing. Available as follows: 38 mm diameter, 5 cm focal length 5 cm diameter, 6 cm focal length 7.5 cm diameter, 7 cm focal length See Enlarge Click to Enlarge Laser Pointer Use as a teaching tool or for science demonstrations. Thin, pen-shaped unit fits in a pocket. Projects a brilliant red dot that's visible even in daylight. Runs for 4 continuous hours on 2 alkaline batteries (included). 5 milliwatt output, 630-680nm wavelength range.

Demonstrate the double refraction present in natural crystal. Our specimen is of the highest optical quality. Size and shape may vary. See Enlarge Click to Enlarge Ulexite (T.V. Stone) Experiment with nature's own fiber optic stone - a rare mineral called ulexite. Its thousands of tiny, parallel crystal "hairs" transfer an image - almost like TV. About 1/2" (13 mm) thick and 3/4 x 3/4" (19 x 19 mm) across the face. Size and shape may vary. See Enlarge Click to Enlarge 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.
