Diffraction In Action!
SPECTROBURST LENS AND LIGHT DIFFRACTION-KIT
For the budding diffraction detective in your life, this Spectroburst™ Viewer is a diffraction-viewing lens and light kit from Spectroclick, which, if you ask us, is a pretty good name for a company that makes Spectroburst™ Viewers. Comes with (2) different diffraction gratings: blue (500 line/mm single dispersion), and red (200 line/mm double-axis) and a magnetic flashlight with solid/flashing modes. You rotate the frames to see kaleidoscopic patterns. Warning: Never look at the sun or a laser directly.
