Optical Power Meter, Benchtop, Single Channel, Power and Energy, RoHS

The 1936-R Single Channel High Performance Optical Power and Energy Meter is one of the most sophisticated optical meters available in the market. The RoHS compliant 1936-R combines superb femtowatt level sensitivity and extreme versatility resulting in a truly revolutionary power meter. All compatible detectors are hot-swappable, avoiding the need to cycle power when a different sensor must be used.

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.

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.
