System Specifications
The 1830-C is compatible with Newport’s Ge, Si and InGaAs detectors, allowing both free-space and fiber pigtailed measurements in the 190–1800 nm range. When using one of these detectors with the 1830-C a calibration module needs to be attached to the detector, assuring the correct reading at any pre-selected wavelength.
