Request InfoMeasures to 10 ppm AccuracyBristol Instruments Inc.VICTOR, N.Y., Aug. 17 -- Bristol Instruments Inc., a new company founded by three former employees of Burleigh Instruments, has introduced its model 521 laser wavelength meter. The model 521 is intended for scientists and engineers who need to know the absolute wavelength of a laser but not to the highest accuracy. The 521 laser wavelength meter uses Michelson interferometer-based technology to measure the absolute wavelength of virtually any continuous wave laser to an accuracy of ± 10 ppm (± 0.01 nm at 1000 nm). A built-in moire scale is used as a reference to provide continuous calibration to...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 2/19/2024Laser Wavelength MetersThe 872A-VIS and 872A-NIR from Bristol Instruments are laser wavelength meters that support laser measurements from 375 to 1700 nm.
