Economy Spectroscope Tube, Pack of 15

Details:

This basic spectroscope allows users to view variable light spectra by holding it up to different lights, observing which wavelengths are present. Light enters through the slit and is split by the diffraction grating at the other end. This makes for a perfect activity for students in school or kids at home. The spectroscope measures 10.25 inches long, with a body diameter of 1 inch and ends that have a diameter of 1.15 inches.
