The new RoHS compliant 1918-R Optical Power Meter, replacing the 1918-C, is the hand-held optical power meter of choice for applications requiring the measurement of continuous intensity or pulse energy of light sources. New 0.5Hz analog filter offers even greater power stability! With patented methods for measuring optical signal characteristics this state-of-the-art optical power meter leverages the advanced features and display capabilities of Newport's 1936-C into a compact, wall-plug and battery powered device, for use in the lab or in the field. The 4 inch, full color, graphical LCD display enables both numerical and graphical measurement representation, with a selection of various color palettes to match filtering properties of users’ laser eye safety goggles.
The 1918-R ships with a full software suite which includes Labview, C++ and CSharp samples.
The 1918-R optical power meter has the ability to handle peak-to-peak measurements of pulses with repetition-rates of up to 4 kHz at a sampling rate of 250 kHz. Pulse, peak-to-peak and DC source measurements can be displayed in units of W, dBm, dB, J, A, V, and Sun, depending on the detector types used.
The 1918-R optical power meter comes with a rechargeable battery, battery charger and carrying case. Batteries are field replaceable by the user and can also be ordered separately.
Note: Use of non-Newport AC adapter will void warranty. For compatibility with Oriel Photomultiplier Tubes and Detectors, Oriel housing 70690 and power supply 70705 will need to be purchased. Please see Related Products tab for additional information regarding Oriel compatible detectors.
Compatible with Photodiode Detectors
Low-power measurements, pW to several Watts (detector dependent) can be accomplished with any one of Newport’s 818 (Low-Power Calibrated Photodetectors) and higher-end 918D Series Low-Power Calibrated Photodetectors UV, Silicon (Si), Germanium (Ge) or Indium Gallium Arsenide (InGaAs) Detectors, covering 200–1800 nm wavelengths The 918D Series Detectors have a built-in temperature sensor utilized for sensing and actively compensating for temperature-induced measurement fluctuations, making them the most advanced photodiode based detectors. Our Calibrated Optical Detector Selection Guide provides a power meter/detector compatibility chart.
Compatible with 818P Thermopile and 818E Pyroelectric Detectors
High-power measurements, in the 1 µW to 20 kW (detector dependent) range can be performed with the 1918-R Series meters utilizing 818P Series Calibrated Thermopile Detectors, operating in the 0.19-11um wavelength range. Energy measurements of pulsed laser sources, from 7 µJ to 20 kJ (detector dependent) can be taken with 818E Series Calibrated Pyroelectric Sensors operating in the 0.19–20 um wavelength range. Pulse repetition rates from single shot to 6 kHz can be measured directly with these instruments, without having to rely on oscilloscope measurements.
Versatile Graphing Capabilities
The Analog Gauge display mode can be used for tuning adjustments. In the Graph screen mode the power meter acts as an oscilloscope. Users can see in real time the optical power level in their experiment.

Advanced Measurement Capabilities
The 1918-R software gives users the flexibility of a command line environment as well as the ability to download collected data directly to a computer for analysis.
Software command line display
You are just a few clicks away from installing Newport's latest Labview samples onto your computer (see Literature and Downloads tab). Labview, CSharp and C++ samples will be installed after a full install of the software.
True Root-Mean-Square (RMS) measurements, providing the most accurate RMS value regardless of the shape of the input waveform.
Additional advanced features include a Stand-by mode for further energy savings, user defined display colors, an internal 250,000 data point storage buffer, additional data storage using an external USB flash drive, analog and digital filtering, programmable sample rates, moving statistics, plotting and multiple user-configuration storage.
Choose the Display Color for Your Needs
Users can select from 6 display colors to match their specific lighting conditions and colors of their laser safety eyewear. Measurements can also be displayed in various display formats, such as numeric, graphic, bar and strip charts.

Detector Compatibility and Performance
The 1918-R Power/Energy Meter is compatible with Newport’s new Low-Power 918D, 818-xx/CM, High-Power 818P and 818E Series Energy Detectors, allowing both free-space and fiber pigtailed measurements in the 190 nm – 20 µm range. All compatible detectors have a built-in or external in-line EEPROM containing detector identification and calibration information. When using an 818-xx/CM Series detector with the 1918-R, the optional 841-DIN adapter is required.
