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 Sensor, 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.

The 1918-C has advanced graphing capabilities

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.

1) Instrument range is determined by detector used. Please refer to our complete offering on detector types for complete specifications of individual detectors: Photodiode (see Low-Power Photodetectors, 918D Series), Thermopile (see Thermopile Detector Sensor, 818P Series) and Pyroelectric (see Pyroelectric Detector Sensor, 818E Series) detectors. Detector Compatibility and Performance The 1918-C 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-C, the optional 841-DIN adapter is required. Detector Compatibility and Performance Table
