Details

Holographic diffraction grating film is used to break up white light into all the colours of the spectrum. It is an ideal choice for spectroscopy experiments, since holographic gratings exhibit significantly sharper diffraction orders than their ruled counterparts by reducing the amount of stray light produced. This results in an increased ability to view absorbtion and emission lines, with higher spatial frequency gratings. Diffraction grating is offered in 1000 or 500 lines/mm. More lines spread the spectrum wider, less lines produce more, narrower spectra - unlike prisms, several spectra, or 'orders' can be produced. Choose from 2", 3" or 6" squares (other sizes are available on request). Please note that this material is highly electrostatic and picks up dust and fingerprints very easily.
