Home / Spectroscopic Systems and Monochromators

This document discusses optoelectronic devices including spectrophotometers and monochromators. What is a monochromator? A monochromator produces a beam of light with an extremely narrow bandwidth, or light of a single color. Spectrographs are important tools for studying many biological and chemical processes and substances, from pigments to plant growth and nucleic acids to pharmaceuticals, providing information about analytes based on their optical properties. In the study of Optical Behaviour of Materials, spectroscopic instruments are used for irradiation of samples as well as for analyzing emitted radiation. The name is from Greek mono- 'single'; chroma 'colour' and Latin -ator 'denoting an agent'.

Monochromator

It is common for two monochromators to be connected in series, with their mechanical systems operating in tandem so that they both select the same color.
