Diffraction Grating $28.00

This diffraction grating is perfect for use in independent dispersion (rainbow) experiments, or as the dispersion element in our student spectrometer. Look at different light sources through it, and compare what you see. What differences do you see between the light from incandescent bulbs and fluorescent lights? How about neon signs?

The grating has an active viewing area of 44 mm x 30 mm, and is ruled at 15,000 lines per inch. Used in a spectrometer, it offers greater linearity of dispersion than a prism.
