Question

Function of dispersion device on spectrometer

Answer 1

A dispersion device on a spectrometer is responsible for separating the different wavelengths of light emitted or absorbed by a sample. This separation allows the spectrometer to analyze the various components present in the sample based on their unique spectral signatures. The dispersion device can be a grating, prism, or other optical element that diffracts and disperses light into its constituent wavelengths. It plays a crucial role in the spectral resolution and accuracy of the spectrometer's measurements.
