Economy Handheld Spectroscope, 6-Pack

This pack of 6 economy spectroscopes allows students to observe the spectrum of light decomposed by a diffraction grating. Each spectroscope measures 10.25 inches long with a 1-inch body diameter and 1.15-inch end diameter. An adjustable thin slit cap rotates to produce diffraction patterns in the desired direction. The resulting spectra introduce students to properties of visible light and optics, enabling quick identification of constituent wavelengths from various light sources. The 6-pack is ideal for classroom use.
