IRVINE, Calif., Aug. 31, 2015 — New Focus (a Newport company) has announced the WM-1210 wavemeter, designed to work in test laboratories and manufacturing environments.
The device provides optical wavelength measurements in the 700- to 1650-nm wavelength range with 1 ppm accuracy and a 20-Hz update rate. It uses a scanning Michelson interferometer that continuously determines the absolute wavelength of a laser source by comparing its interference fringe pattern with that of an internal HeNe laser standard.
Applications include the wavelength calibration of tunable and swept laser sources; wavelength monitoring in distributed-feedback, tunable and vertical-cavity surface-emitting lasers; and atomic spectroscopy.
