A spectrum splitter is an optical device designed to separate light or other forms of electromagnetic energy into its component wavelengths. This process is fundamentally different from a simple power divider, which merely reduces signal strength across multiple outputs. It decomposes compound light into monochromatic light of different wavelengths through the dispersion property of prisms, so as to achieve the. A spectrometer is nothing more than a device to split light into its different colors (a prism or a diffraction grating) that projects onto a camera (usually a CCD chip). Robert Bunsen invented his Bunsen burner not for heating laboratory equipment, but for use in flame tests and spectroscopy. We make use of this in many ways, for example in glow-in-the-dark stickers. The technique ties light behavior to molecular structure, giving direct insights into chemical bonds and functional groups.
