WebApr 7, 2024 · Dispersing device, commonly a grating or a prism Focusing lens Exit slit Polychromatic radiation or radiation of multiple wavelengths will enter the monochromator from the entrance slit. The beam will collimate and strike the dispersing element through a specific angle and split into several component wavelengths using the prism or the grating. 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. how to take post office to court
