Optical spectrometer
Optical spectrometers (often simply called "spectrometers"), in particular, show the intensity of light as a function of wavelength or of frequency. The different wavelengths of light are separated by refraction in a prism or by diffraction by a diffraction grating. Ultraviolet–visible spectroscopy is an example. These spectrometers utilize the phenomenon of optical dispersion. The light fr… WebOptical Emission Spectroscopy (OES) is a fundamental, non-invasive diagnostic technique for a wide range of plasma, and can provide information such as composition and species temperature and energy distribution. Laser-induced breakdown spectroscopy (LIBS) is used to determine the elemental composition of various solids, liquids and gases.

WebAlthough there are many designs, the core of any optical spectrometer is some component that separates light by wavelength. Most commonly this component is a diffraction grating – a sheet of material etched with repeating grooves that causes light reflected from it or transmitted through it to diffract and bend at an angle proportional to its wavelength. WebSpectrometers & Signal Detectors Thorlabs offers complete optical spectrum analyzers for FTIR measurements over the near-UV to mid-IR wavelength ranges. Our holographic grating spectrometer is also fiber-compatible and can be easily integrated into an OCT system.
