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 WebUsually X-ray diffraction in spectrometers is achieved on crystals, but in Grating spectrometers, the X-rays emerging from a sample must pass a source-defining slit, then optical elements (mirrors and/or gratings) disperse them by diffraction according to their wavelength and, finally, a detector is placed at their focal points.

$An Introduction to a Spectrometer - Diffraction Grating$

WebThe grating is used as a dispersive element to disperse the wavelengths of light. Properties of the grating do not only include its dispersion range but also influence the optical … WebRaman spectroscopy belongs into the category of vibrational spectroscopy. This means that it analyzes a sample chemically, by using light to create (excite) molecular vibration, and interpreting this interaction afterwards. It is based on the inelastic scattering of light that occurs when matter is irradiated by light.
