Infrared Absorption Spectroscopy Lasers

Infrared Absorption Spectroscopy Lasers

Infrared absorption spectroscopy takes advantage of the fact that all covalently bonded molecules have vibrational absorption bands whose energy corresponds to infrared wavelengths with overtones in the near infrared.  As a result, when infrared light is incident on the sample the wavelengths corresponding to the vibrational modes will be absorbed.  In traditional infrared spectroscopy broadband light sources are used to illuminate the sample and see which bands are absorbed, but when you are looking to identify specific bands of infrared absorption, spectroscopy lasers can be used to target those particular bands.  Depending on the set-up, infrared absorption spectroscopy lasers can either be fixed wavelength or tunable but in either case; they must be wavelength stabilized to assure accurate and repeatable results.  On this page, you will find a list of all of the infrared spectroscopy lasers we offer including both tunable DFB and Fabry-Perot diode lasers, as well as fixed wavelengths volume Bragg grating, stabilized diode lasers.
