Researchers have developed a new type of spectrometer using tiny mechanical and optical components. This device can analyze different wavelengths of light quickly and accurately. Unlike traditional spectrometers, it uses a single detector that is cheaper and works for all wavelengths. The spectrometer is small, lightweight, and can withstand shocks and vibrations. It can scan a whole spectrum in just milliseconds, thanks to a moving grating. This technology allows for high-resolution measurements at a lower cost compared to other spectrometers on the market.
