Features
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.
Analog Gauge display
Highly Visible Color Display
The 5.7 inch, full color, graphical LED display provides excellent legibility from any angle, in any light condition. It enables both numerical and graphical measurement representation, with a choice of six different display colors. Measurements can also be displayed in formats including numeric, graphic, bar and strip charts.
Software suite including LabVIEW™ and C# samples
The application software, common for 1830-R series and the discontinued 1918-R optical power meter, gives users the flexibility of a command line environment as well as the ability to download collected data directly to a computer for analysis. Advanced programming toolkits such as LabVIEW™ and .Net C# samples will be installed automatically when installing the application software. Basic USB communication setup programming samples are also provided in C++ and Visual Basic.

Advanced Measurement Capabilities
The 1936-R and 2936-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. True Root-Mean-Square (RMS) measurements, providing the most accurate RMS value regardless of the shape of the input waveform. Additional advanced features include 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.
Extreme Versatility from State-of-the-Art Electronics
For applications requiring measurement of low-power, high-power or energy of continuous or pulsed light sources, Newport’s 1936-R and 2936-R instruments have broken the barrier of temporal measurement performance with calibrated results. This series of power and energy meters have the ability to handle repetition-rates of up to 10 kHz at an unheard sampling rate of 250 kHz. This means that even reasonably high speed dynamical phenomena can be seen using the meter, eliminating a need for an oscilloscope in many cases.
Various Measurement Units
Pulse, peak-to-peak and DC source measurements can be displayed in units of W, dBm, dB, J, A, and V depending on the detector types used. It can handle peak-to-peak measurements of pulses with repetition-rates of up to 4 kHz at a sampling rate of 250 kHz.
Modulated or Pulsed Light Measurement
Newport’s high bandwidth design allows calibrated power measurements of highly fluctuated, modulated, or pulsed sources using photodiode detectors. Frequency measurements can be made in the 1 Hz up to 250 kHz range, using Newport’s Low Power 918D and 818 series photodiode detectors and 819C/D series integrating sphere detectors.
Calibration Report Included
Newport certifies calibration performed using standards traceable to the National Institute of Standards and Technology (NIST) and other recognized national standards laboratories. Included with your new instrument is a comprehensive calibration report. Newport also recommends recalibration every 12 months.
Additional Benefits
Color plotting, statistics and on-board data post-processing
USB and RS-232 computer interfaces
Analog bar graph with 10X zoom
Accelerated thermopile based power measurements with fast prediction algorithm
USB data transfer up to 11 Mbps
