Spectrometer, Project Star
Explore flame spectra, streetlights and solar spectra with this dependable device. 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.
Spectroscope Set/15
Show that white light is composed of many colors. Examine the effects of color filters. Each student can assemble his own spectroscope and experiment with incandescent, neon and fluorescent tubes. Set of 15.
Spectroscope, Metal
This direct vision hand-held device shows spectra of the first and second orders. View the bright lines of metal in flames, gases and the absorption spectra of solutions and colored glass. Metal body with durable prisms and lenses.
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.
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.

Triangular Block, Equilateral, Glass
To demonstrate diffraction, spectrum formation & dispersion.
Polished edges. Dimensions 75mm side x 10mm thick.
Triangular Block, Right Angle, Glass

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.
