The 8471 is an optical wavelength meter that uses a helium-neon laser as reference wavelength and employs the Michelson interferometer method, providing high-accuracy measurement. It performs high-resolution, highly accurate measurements of emission center fre of laser diodes for DWDM. 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.
