Holographic Diffraction Grating Film (unmounted) 500 lines per mm - 2

Curious Minds · Compare 1 offer

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 emissio...
