Holographic Diffraction Grating Film (unmounted) 1000 lines per mm
Holographic diffraction gratings are used to diffract white light into a spectrum. They are optically generated by recording an interference pattern on a photorestist-coated substrate.
They are ideal for use in spectroscopy experiments as the diffraction orders are significantly sharper than their ruled counterparts. This is due to the reduction in stray light produced which allows for an increased ability to view absorption and emission lines. At 500 lines per mm, the wavelengths of the diffracted light lie between 400 and 700 nanometers with a dispersion angle of 19 degrees.
The diffraction grating is made from clear polyester film with a thickness of 0.0762mm and is available in 2, 4 and 6 square inches.
