Request InfoBristol Instruments Inc.The 521 Series laser wavelength meter from Bristol Instruments is a compact system that provides reliably accurate laser wavelength measurement, intended for scientists and engineers who need to know the absolute wavelength of their laser but not to the highest accuracy available. The 521 Laser Wavelength Meter uses Michelson interferometer-based technology to measure the absolute wavelength of virtually any CW laser to an accuracy of ± 10 ppm. The model 521 uses a Moire scale as a built-in reference. This high-resolution scale provides the continuous calibration necessary to guarantee...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra October 2022 IssueLaser Power MeterThe LabMax Touch Pro laser power meter from Coherent Inc. makes data acquisition and analysis for nW continuous wave lasers up to multi-kW, pulsed industrial lasers easy to access through an...Photonics Spectra January 2024 IssueCompact Laser WorkstationThe M1000 from FOBA Laser Marking & Engraving is a compact laser workstation with an integrated 3W UV / 5W UV / 10W green laser.
