New Focus offers 700-1650 nm optical wavemeter

New Focus, a Newport Company, has unveiled the WM-1210 optical wavemeter. The first such instrument from the company, the WM-1210 is designed to be easy to use, with minimal setup, and provide optical wavelength measurements in the 700- to 1650-nm wavelength range with ±1 ppm accuracy and 20 Hz update rate.

New Focus, a Newport Company, has unveiled the WM-1210 optical wavemeter. The first such instrument from the company, the WM-1210 is designed to be easy to use, with minimal setup, and provide optical wavelength measurements in the 700- to 1650-nm wavelength range with ±1 ppm accuracy and 20 Hz update rate.

The company has aimed the test and measurement instrument at test lab and manufacturing applications. Applications include the wavelength calibration of tunable and swept laser sources; the wavelength monitoring of DFB lasers, tunable lasers, and VCSELs; and atomic spectroscopy.

The system 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. The built-in HeNe laser automatically calibrates the wavemeter, New Focus explains.

The WM-1210 also has a large display and full front panel control for standalone use. In RS-232 and USB interfaces support computer control. The wavemeter also comes with software that provides users with control of the device and enable full integration into their systems.
