Request InfoBristol Instruments Inc.Bristol Instruments Inc. has introduced a wavelength meter for use with tunable quantum cascade lasers. The new 621B-MIR measures absolute wavelength of CW lasers that operate from 4 to 11 μm. Reliable accuracy of ±1 part per million is achieved because of continuous calibration with a built-in wavelength standard. Now researchers working at mid-IR wavelengths for high-resolution spectroscopy, photochemistry or optical sensing applications can achieve more meaningful experimental results with accurate laser wavelength information.See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Nov/Dec 2022 IssueRaman InterfaceThe inLux™ scanning electron microscope (SEM) Raman interface from Renishaw PLC enables in situ Raman spectroscopy for highly specific chemical and structural characterization.
