Request InfoBristol Instruments Inc.The best way to determine the absolute wavelength of CW lasers is with the 621 Series Laser Wavelength Meter. This system provides real-time wavelength information measured to an accuracy as high as ±0.2 parts per million. This accuracy is guaranteed by continuous calibration with a built-in wavelength standard which ensures the reliable accuracy that is needed to generate the most meaningful experimental results. Two versions of the 621 series are available. The model 621A is offered for the most demanding experiments, measuring absolute laser wavelength to the highest accuracy...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...BioPhotonics Jan/Feb 2024 IssuePortable Wideband LaserThe SLP-1000 from SuperLight Photonics is a portable wideband laser.
