DescriptionSpecifications Models Literature

The 1918-C Optical Power Meter is the hand-held optical power meter of choice for applications requiring the measurement of continuous intensity or pulse energy of light sources. This state-of-the-art optical power meter leverages the advanced features and display capabilities of Newport's 1936-C (Optical Power and Energy Meters, High Performance, 1936-C/2936-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-C 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 100 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-C 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.

Compatible with Photodiode Detectors

Low-power measurements, pW to several Watts can be accomplished with any one of Newport’s 818 (see Low-Power Photodetector, 818 Series) and higher-end 918D Series UV, Silicon (Si), Germanium (Ge) or Indium Gallium Arsenide (InGaAs) Detectors, covering 190–1800 nm wavelengths (see Low-Power Photodetectors, 918D Series). 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. Please see Optical Detector Selection Guidefor a power meter/detector compatibility chart.

Compatible with 818P Thermopile and 818E Pyroelectric Detectors

High-power measurements, in the 1 µW to 20 kW range can be performed with the 1928-C Series meters utilizing thermopile detectors (see Thermopile Detector, 818P Series), operating in the 0.19-11um wavelength range. Energy measurements of pulsed laser sources, from 7 µJ to 20 kJ can be taken with pyroelectric detectors (see Pyroelectric Detector Sensor, 818E Series) 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

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.Users can change the display mode to analog, for fine adjustments.

Advanced Measurement Capabilities

True Root-Mean-Square (RMS) measurements, providing the most accurate RMS value regardless of the shape of the input waveform.

Additional advanced features include 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.
