Newport 1918-R Hand Held OPM

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. 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.
