Quantitative Spectroscope #10010 Reveal the hidden nature of color and visible light with this durably constructed, economical spectroscope. Begin investigating bright line spectra to unveil the atomic origin of light the instant you pick up this hand held spectroscope. Contrast the differences between gas discharge (fluorescent) and incandescent lights. Discover the workings of diffraction gratings and how they separate white light into its component colors. Measure the wavelengths of visible light from 4000 to 7000 Angstroms with the precision of +/- 50 Angstroms using the built in scale. Supplied with an excellent set of instructions that reviews the historical aspects of light theory, diffraction gratings, and provides suggestions for numerous experiments to help you unlock the world of visible light.

Diffraction Materials Card #10030 Is it a wave or is it a particle? Use this handy card containing 5 different materials to investigate the effects of diffraction, and explore the fundamental questions of quantum mechanics! This card can be used as a demonstration aid to discuss the qualitative nature of diffraction or it can provide an easy introduction to a more quantitative analysis using Young's equations for diffraction. Quickly and easily demonstrate the relationships between line width, wavelength, and diffraction angle. In a laboratory setting, measurements of the diffraction pattern can be used to calculate the wavelength of laser light used. Or knowing the wavelength of the laser, calculate the line spacing of the grating. A must have for any discussion of optics!

Spectroscope Light Source Adaptor #10120 This kit includes one universal adaptor for use with any hand held quantitative spectroscope (1 inch thick or less) and a set of 4 chemiluminescent light sources (red, orange, green, blue). The universal adaptor can be used when viewing both emission and absorption spectra and will hold samples in any cylinderical container up to 1 inch in diameter. The adaptor is simply clipped over the spectroscope in front of the entrance slit, and the thumb screw lightly tightened. Just press any of the provided chemiluminescent samples into the adaptor's special groove and you're ready to go. For larger samples, a rubber band can be used to hold a test tube (or vial) in the v-notch of the adaptor. Includes instructions that illustrate the use of the adaptor and light sources as well as additional information about chemiluminescence. Preview the Instructions Here (180 KB PDF) $12.50 each |

Chemiluminescent Light Sources #10130 Discover how chemical reactions can emit light with this package of 9 different chemiluminescent light sources (red, pink, orange, yellow, green, aqua, blue, purple, and white). Each mini light stick is 3/16 inch in diameter and 1 ½ inch long and will emit light for approximately 2 hours. They can be used as stand alone light sources to study chemiluminescence and the temperature dependence of chemical reactions, or as replacement light sources for the Spectroscope Light Source Adaptor #10120 to demonstrate molecular emission spectra. These light sources are non toxic and non flammable. $10/package |
