A large number of parallel, closely spaced slits constitutes a diffraction grating.
They are also referred to as 'super prisms'.
They are used to split and diffract light into several beams travelling in different directions. The emerging coloration is a form of structural coloration.
The directions of these beams depend on the spacing of the grating and the wavelength of the light.
Students can enjoy the creation of "rainbow" colors when these diffraction gratings are illuminated by a wide spectrum (e.g., continuous) light source.
With experiments utilizing diffraction gratings, students can understand the diffraction grating equation and the relationship between the spacing in the grating, and the wavelength of the light.
Diffraction gratings available with us include:
- Diffaction Grating 100 lines/mm in 50 × 50mm mounts.
- Diffaction Grating 300 lines/mm in 50 × 50mm mounts.
- Diffaction Grating 600 lines/mm in 50 × 50mm mounts.
