1 2 3 4 [5] [«Back ]   Click to Enlarge Quantitative Spectroscope 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. Don't forget to add the Light Source Adaptor, or a set of 9 Chemiluminescent Light Sources to expand the capabilities of your spectroscope! See Enlarge Click to Enlarge Spectrum Tubes These tubes produce bright, well-defined, unique spectra when the gas inside is excited before a spectroscope. Of glass construction, 26 cm long and narrowed to capillary width for about 10 cm in the center. Sealed metal wires hold the electrodes and are welded to metal caps which have a loop for convenient hookup to wire connections. You need 614-0795 Spectrum Tube Power Supply, not included. Varieties as shown in table below. See Enlarge Click to Enlarge Spectrum Tube Power Supply This is a convenient and safe way to excite the gases in spectrum tubes for viewing with a spectroscope. Specially designed shield holds the tube in place. For use with spectrum tubes. See Enlarge 1 2 3 4 [5] [«Back ] Go to Top
