Function of a Spectrophotometer Monochromator
Monochromators are the components in spectrophotometers that can isolate, select, and scan through different wavelengths of light. Learn what they are, how they work, and their uses. Justin Tom received his PhD in chemistry in 2018 under the supervision of Professor Heather Andreas at Dalhousie University. The name is from Greek mono- 'single'; chroma 'colour' and Latin -ator 'denoting an agent'. There are numerous configurations by which this may be achieved; only the most common are discussed in this document, including Plane Grating Systems (PGS) and. Because of this, gratings are commonly used in monochromators of spectrometers. When there is a need to separate light of different wavelengths with high resolution, then a diffraction grating is most often the tool of choice.
