Diffraction Gratings 300/600 Lines.

Available in 300 lines/mm or 600 lines/mm.

Made from glass or plastic with closely spaced lines ruled or holographically produced on the surface.

Spectroscopy: To disperse light into its components (forming a spectrum)

Physics demonstrations: Showing diffraction, interference, and wavelength separation

Educational: Valuable for understanding the properties of light and for measuring spectral lines
