Monochromators vs Polychromators: Wavelength Selection Strategies
Understanding Monochromators Monochromators are devices that isolate a single wavelength of light from a broad spectrum. They employ dispersion elements such as prisms or
Commonly used spectroscopic elements in monochromators
The basic elements of a monochromator are (1) entrance slit, (2) collimating mirror (to form a parallel beam after the slit), (3) diffraction grating (dispersive element), (4) camera mirror (focuses light from the dispersive element onto the exit slit), and (5) exit. The basic elements of a monochromator are (1) entrance slit, (2) collimating mirror (to form a parallel beam after the slit), (3) diffraction grating (dispersive element), (4) camera mirror (focuses light from the dispersive element onto the exit slit), and (5) exit. Monochromators are an essential part of many spectrometers. Learn what they are, how they work, and their uses. Justin Tom received his PhD in chemistry in 2018 und...
