The Model 840-C hand-held optical power meter is fully compatible with all of Newport’s 818 Series Low-Power Si, Ge and InGaAs detectors. Detectors connect to the power meter through an in-line calibration module that is dedicated to each detector (see System Specifications Table below for all compatible detectors). These detachable modules provide the Model 840-C with calibration and operating information specific to the assigned detector. Various detector accessories allow for free-space, as well as for fiber coupled power measurements. DC and AC peak-to-peak power measurements can be displayed in units of W and dBm on the instrument’s 4 digit, backlit LCD. * Features/Specifications: * Power and precision typical of a benchtop meter * Includes both DC and AC peak-to-peak measurement modes * Power sensitivity from 100 pW to 2 W (-70 to +33 dBm) * Wavelength and range settings * Linear, dB, dBm and linear ratio readouts * Background subtraction and digital averaging
