A spectrometer is a photometer that detects the composition of substances by passing light through a sample and comparing before and after wavelength intensities. The instrument performs over a range ...

Each type of light source has its own spectral distribution that show the proportions between individual wavelengths. Using spectral distributions, qualitative aspects of light such as color and color ...

Meet the world’s smallest optical spectrometer. Crafted from a single nanowire less than 100 µm long, the device can measure the intensity of colored light across the visible spectrum and may ...
