For decades, bulky spectrometers have been the main tools for understanding how things are made of chemicals (a thing called composition). Spectrometers are a type of lab equipment that uses prisms or ...

For decades, bulky spectrometers have relied on prisms and gratings to split light into component colors, demanding long optical paths and large lab setups.
