The Newport 1830-C Picowatt Digital Optical Power Meter is a high-resolution benchtop instrument engineered for precise DC optical power measurements from 100 fW to 2 W. It delivers autoranging across up to 8 decades and integrates with Newport’s 818 Series silicon, germanium, and InGaAs detectors for applications spanning 190–1800 nm. The meter combines exceptional accuracy (±0.2% typical) with intuitive front-panel operation, making it ideal for production testing, component characterization, and laboratory power verification in fiber optic and photonic systems.
Technical Specifications
• Measurement Range: 100 fW to 2 W (with OD-3 attenuator); up to 8 signal decades depending on detector

• Wavelength Range: 190–1800 nm (detector-dependent; 200–1100 nm for 818-UV/CM; 780–1700 nm for 818-IR)
• Wavelength Adjustment: 1 nm resolution steps from front panel
• Update Rate: 75 ms per reading
• Auto-Range Time: 200 ms typical
• Analog Output: 0–2 V into 1 MΩ (proportional to detector current)
• Power Supply: 100–120 V AC or 220–240 V AC, 50/60 Hz
– Key Features
• Relative power measurements (ratio or dB mode)
• Audible tone for beam alignment optimization
• RS-232C and IEEE-488 (GPIB) interfaces for remote control and data logging
• Compatible with Newport calibration modules (8-pin Sub-mini DIN connector) attached to 818 Series detectors
• Compact benchtop form factor with minimal footprint
– Typical Applications
• Production testing of fiber optic components and assemblies
• Optical power verification in photonic systems
• Low-level signal detection and measurement
• Wavelength-dependent power characterization
– Compatibility & Integration
The 1830-C accepts Newport 818 Series silicon, germanium, and InGaAs detector heads. A calibration module must be installed on the detector for accurate readings at specified wavelengths. LabVIEW driver samples are available; remote command syntax and computer interface protocols are documented in the instruction manual. The 1830-R Benchtop Optical Power Meter serves as a redesigned drop-in replacement.
