- ADCMT Optical Wavelength Meter 8471
Optical wavelength meter capable of high-accuracy and high-speed measurement
The 8471 is an optical wavelength meter that uses a He-Ne laser as reference wavelength and employs the Michelson interferometer method, providing high-accuracy measurement. It can measure emission center frequencies of laser diodes for DWDM with high resolution and accuracy. The 8471 even provides a high sampling rate of 10 times per second, and is suitable for oscillation wavelength adjustment. In addition, its deviation display function allows wavelength variation to be measured with high resolution and accuracy.
