Educational Diffraction Grating 3-in-1

For demonstrating the principle of the diffraction grating and the way in which the properties are dependent upon the number of lines per unit length. Comprises a mask mount 90 x 30mm approximately with three 16 x 9mm apeture, each containing a diffraction grating replica.
The gratings are of 100 lines/mm, 300 lines/mm and 600 lines/mm respectively and are protected by glass plates. Sealed with Black Tape.
Apparatus required: Used with Spectrometer only.

Package Contains:
1. Diffraction Grating - 1 No.
2. Box - PP/ABS - 1 No.
