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 MediaPRODUCTSPhotonics.com 2/29/20243D Measuring DeviceThe FocusX from Bruker Alicona is an optical 3D measuring device meant for applications where highly reflective surfaces, steep flanks, and complex forms must be measured.
