Light & Color Three intriguing, hands-on ways to explore the properties of light and color 1. Rainbow Glasses The Easiest Way Ever to Use a Diffraction Grating! 3. 3-D glasses — View Flat Graphics in 3-D! 2. HoloSpex Glasses: Bend light to create magical holographic illusions. These popular glasses offer you a cost-effective way to utilize diffraction gratings in class. Your students will be delighted when they see the unique rainbows produced when they look through the double-axis lenses at different light sources and gas discharge tubes. P3-6300 Single glasses $1.25 each 10 or more $.75 each 1. Rainbow Glasses: View the rainbows created by gas discharge tubes and light sources. These glasses use both refraction and diffraction to shift the colors of any picture, computer image, TV image, or laser light show to different angles according to their wavelengths, thus tricking the mind’s natural way of perceiving depth. Complete Kit includes 15 glasses, viewing sheet, and Windows software. Explanation and instructions for making your own images are included. P3-6100-01 P3-6100 Complete kit Single glasses 10 or more $32 $2.50 each $1.85 each 2. HoloSpex Glasses Turn a light string into a string of colorful snowflakes! HoloSpex lenses have a computer-generated pattern of curved lines (rather than the usual straight parallel lines) and use diffraction, nodes and antinodes to create a specific pattern. The best images are produced by point sources of light like small incandescent bulbs. P3-6200 Single glasses $2.50 each 10 or more $1.85 each 3. 3-D Glasses: Refraction and diffraction combine to produce true 3-D images. Diffraction Grating Glasses Classroom Set Get all three glasses in one affordably priced kit. You’ll get 15 Rainbow Glasses, 15 3-D Glasses with viewing sheet and software, 15 HoloSpex, light string, and an easy-to-read explanation and activities pamphlet. BUY! BEST P3-6400 $70 Chemiluminescent Color Addition! Snap the red, blue, and green light sticks and attach them to the axle. Dim the lights, turn the crank, and observe a circle of white light! Add pieces of black tape (included) to create bands of color. For instance, if you put tape over part of the blue light stick, you will see a band of yellow color in that area when the wheel spins. Includes crank wheel and sturdy table-clamp base (up to 3.5 cm opening), primary colored light sticks, black tape, and complete instructions. Batteries not included… you don’t need any! P2-9440 RGB Snap Lights & Spinner $35 P2-9445 Replacement light sticks (Set of 3) $6 10 or more $5.50 Kit includes Holographic Diffraction Grating, Projector mount, slit and anti-slit masks, color filters with spectral graphs, and instructions Spectrum Demonstration Kit — Tired of the tiny spectrum that results from a prism? Teach about color and spectroscopy with this complete kit. Mount the grating on the top of your overhead projector, and project a broad, bright spectrum on the wall. Use the color filters to show color addition and subtraction, and use the unique “Anti-slit” mask to show complementary colors. 33-0200 Spectrum Demonstration Kit $19 7 6 5 4 3 A built-in scale measures light wavelengths from 400 nm to 700 nm with a precision of +/- 5 nm. An easy, economical way to see and measure light from different sources. Bright, clear, and durable, our spectroscope lets students see light from different sources separated into component colors. Use with spectral tubes, ordinary light sources (fluorescent, incandescent, halogen, mercury) around the school, or our specially-designed miniature light sticks and adaptor. P2-7061 A. P2-7062 B. P2-7063 Quantitative Spectroscope 10 or more Light Source Adaptor Replacement Light Sources 9/pk $10 $9 $15 $14 New table clamp mounting! A B (includes four different chemiluminescent light sticks) This actual photo shows that a gentle twist of the handle is all it takes to produce white light and secondary colors. 6 1-800-367-6695
