DIFFRACTION GRATING SLIDE 3 IN ONE EDUCATIONAL

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 90x40mm approximately with three 16x 9mm apertures, each containing a diffraction grating replica. The gratings are of 100lines/ mm. 300lines/ mm and 600lines/ mm, respectively and are protected by cover glasses.
