This family of InGaAs and Ge detectors covers the spectal information rich 0.7 to 2.5 µm NIR measurements. These detectors are operated in the photovoltaic (unbiased) mode to provide the lowest noise for DC and low frequency operation since it avoids the shot noise associated with bias currents. One unit, model 71898, comes with a DC bias arrangement producing 1 ns rise times. We offer amplified and un­amplified, calibrated and non calibrated models, as well as TE cooled and room temperature versions. Their large areas make signal capture easy. The 1.5 Inch Series flange allows instant connectivity to other Oriel instruments, such as monochromator exit slit assemblies. Use the Ge detectors to get beyond the 1.6 µm limit of standard InGaAs.
