For demonstrating the principle of the diffraction grating and the way in which its properties are dependent upon the number of lines per unit length. Comprises a card mount 90 x 40 mm approximately with three 16 x 9 mm apertures, each containing a diffraction grating replica. The grating are of 100 lines / mm, 300 lines / mm and 600 lines /mm respectively and protected cover glasses.
