WebThe spectrophotometer uses a lens system that focuses the light towards an open slit. This light is then focused towards an exit slit using a second lens so the monochromatic … A monochromator can use either the phenomenon of optical dispersion in a prism, or that of diffraction using a diffraction grating, to spatially separate the colors of light. It usually has a mechanism for directing the selected color to an exit slit. Usually the grating or the prism is used in a reflective mode. A reflective prism is made by making a right triangle prism (typically, half of an equilateral prism) w… WebA spectrometer consists of (1) an entrance slit, (2) a diffraction grating or prism, (3) a detector, (4) routing optics, and (5) higher order filters. ... The diffraction order of interest is directed back towards the mirror, where it is reflected towards the exit slit, which is spatially very close to the entrance slit. ... examples of teamwork in school
