The Newport 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. 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.
The 840-C is compatible with Newport»s Ge, Si and InGaAs detectors, allowing both free-space and fiber pigtailed measurements in the 200–1800 nm range. When using 818 Series detectors with the 840-C, a calibration module needs to be attached to the detector (818-xx/CM), assuring the correct reading at any pre-selected wavelength. Newport»s new 918D and 918L Series detectors can also be used with the 840-C, in combination with the 818P-DIN adapter.
