ESAW Three-in-one Laser Grating (MP-3327)

MP-3327 - ESAW Three-in-one Laser Grating

For demonstrating the principles of the diffraction grating and the way in which its properties are dependent upon the no. of lines per unit length. The gratings are 100lines per inch, 300lines per inch or 500lines per inch respectively. All are mounted in one frame.
