ANDO AQ6141 Multi-Wavelength Meter

The ANDO AQ6141 Multi-Wavelength Meter is a precision optical instrument for measuring wavelengths across the 900 to 1680 nm band. It delivers absolute accuracy to ± 0.2 ppm in the 1270–1680 nm range and provides simultaneous waveform and measurement display with peak analysis capabilities. The meter accepts single-mode fiber input at power levels to +10 dBm and features advanced analysis tools including 3D waveform visualization, ITU-T grid verification, wavelength drift measurement, and dual marker functions. Built for DWDM system development, optical component characterization, laser wavelength verification, and narrow bandpass filter testing, the AQ6141 combines high spectral resolution with laboratory-grade stability.
