Spectroscopy

Optical spectroscopy is a technique that analyzes how light interacts with matter to reveal the spectral characteristics of a sample. By using an optical spectrometer to measure light intensity across wavelengths, users can determine a sample’s composition through precise, non-destructive analysis. Optical spectrometers typically utilize diffraction gratings or prisms to disperse light and capture detailed spectral data. Spectrometers are used across a wide range of applications including material identification, environmental testing, display and light source calibration, and optical metrology.

Edmund Optics offers a range of optical spectrometers and compatible accessories. Our selection includes gas cells, reflectance standards, phantom samples, fiber optics, and light sources—along with optical elements such as filters, lenses, and gratings for custom system integration. Whether you're building a custom solution or seeking a turnkey system, our spectrometers support UV-VIS spectroscopy, NIR spectroscopy, fluorescence, and Raman applications, making them ideal for laboratory, industrial, or OEM use.
