From photon to signal
Measured response depends on the InGaAs spectral variant. The range datasheet also specifies gain-dependent noise, full well, integration modes and cooling conditions.

Original curve for this spectral-window model from SWIR range Rev01. Curves for standard, Vis-SWIR, XT and XT+ sensors are distinct; the published numerical QE points are shown above.
Manufacturer response curve from the earlier individual-camera sheet; source revision and axes are retained. This is separate from the SWIR range Rev01 curve.
