A chart and pocket-sized viewer that shows the color spectra of common night lights, identifies each spectrum, and includes a diffraction grating through which you can see them. You can easily survey the night light spectra while riding around after dark, holding Night Spectra Quest up to your eye, with someone else driving. Booklet also includes further information and experiments.

To study Spectral Lines of Pure Elements / Gases. Gas under pressure in the tubes is used to produce a light for spectral analysis. Brightness of light depends on the nature of gas. Optimum intensity, line resolution and longer life. Metal ends with long life electrodes. About 26 cm long, with 90 -100 mm of central capillary. For intermittent use only, not to be used as a lamp source. These are designed to operate 30 seconds ON~30 seconds OFF. Need Spectrum Tube Power Supply or an Induction Coil, sold separately.
