The Newport 1930F-IG is a single-channel fiber optic power meter built around an InGaAs detector for precision optical power measurement across the 800–1650 nm wavelength range. It delivers high sensitivity and wide dynamic range performance, measuring optical power from 200 fW to 2 mW (−97 dBm to +3.0 dBm) with ±5% accuracy and ±0.5% linearity. The instrument measures both continuous wave and modulated signals across seven selectable gain ranges, making it suitable for telecommunications, research, and manufacturing environments.
