diffraction gratings on glass plate

The Diffraction Gratings on Glass Plate comprises a glass plate with three diffraction gratings with differing numbers of lines, for quantitative diffraction experiments. The glass plate is chromium-coated, with diffraction objects of high precision and regularity applied by microlithography. The glass supports are highly resistant against ageing and contamination.

The product can be combined with the Component Holder on Stem , enabling it to be used with optical riders and optical benches for a range of demonstrations and experiments related to diffraction.
