WebBasically, a spectrometer is an optical system consisting of two lenses or mirrors that produce an image of the input slit on the detector. In between the lenses or mirrors, a diffraction grating is placed that disperses different wavelengths from different angles. WebSep 12, 2024 · Diffraction gratings are commonly used for spectroscopic dispersion and analysis of light. What makes them particularly useful is the fact that they form a sharper pattern than double slits do. That is, their bright fringes are narrower and brighter while their dark regions are darker. tsh biochemistryhttp://www.cchem.berkeley.edu/grfgrp/Papers/1995%20Joo%20OptLett20.pdf philosophers cup
