Monochromator Continuous Spectroscopy

The monochromator comprises a dispersive element, an entrance slit and mirrors to create a parallel beam similar to sunlight, and an exit slit and mirrors to extract the monochromatic light. The prism and diffraction grating are typical dispersive elements. Table 1 shows their. A monochromator is an optical device that transmits a mechanically selectable narrow band of wavelengths of light or other radiation chosen from a wider range of wavelengths available at the input. The most common design is the Czerny-Turner monochromator. The. Multichannel spectroscopy involves the detection of optical signals using an array of detectors to capture the entire desired spectrum at once or after a few scans of the grating.
