How does a grating spectrometer work
WebDiffraction gratings allow optical spectroscopy. A grating is a set of equally spaced, narrow, parallel sources. A grating disperses light of different wavelengths to give, for any … WebA grating divides the light available into different segments. Gratings are common in spectrophotometers that use UV, visible and infrared regions. Sample Chamber The sample chamber is where the operator inserts the sample for analysis. Samples are typically placed into a cuvette made of a material such as glass or quartz. Detector
