Basic spectroscopes able to view variable light spectra
Hold it up to different lights to observe which wavelengths are present
Light enters through the slit and is split by the diffraction grating at the other end
Perfect activity for students at school or kids at home
Spectroscope measures 10.25″ long. Body has a diameter of 1″, and ends have a diameter of 1.15″

This is a basic spectroscope that can view spectra emitted by light sources. It’s lightweight, easy to use, and makes a great activity both in the classroom and at home. Experiment with different kinds of lights both indoors and outdoors. Grating has 500 lines/mm. Spectroscope measures 10.25″ long. Body has a diameter of 1″, and ends have a diameter of 1.15″.
