Ando AQ6310B 400-1750nm Optical Spectrum Analyzer

The Ando AQ6310B is a precision optical spectrum analyzer for characterizing light sources, optical fibers, filters, and optical components across the 400–1750 nm wavelength range. It delivers wavelength accuracy to ±0.5 nm at 25°C and ±1 nm across the operating temperature range, with resolution bandwidth selectable from 0.1 to 10 nm depending on wavelength region. The instrument measures optical power from −70 to +10 dBm across its full range, with extended sensitivity to −80 dBm in the 600–1600 nm band.

High-speed sweep capability completes 100 nm spans in 1 second or less.
