The high resolution Xlin-1.7-3000
InGaAs detector is specically designed
for earth observation. The detector is
based on mechanical butting of three
InGaAs photodiode arrays with each
1024 pixels on a 25 µm pixel pitch,
forming a nearly continuous line of
2900 pixels. The sensors come in an
hermetically sealed package with an
anti-reective coated window or in an
open package (optional).

Wavelength (nm)

Thanks to their high sensitivity and
quantum efficiency they operate at very
low illumination levels.

The read-out integrated circuit includes
Correlated Double Sampling (CDS) and
autozero features, enabling low Dark
Signal Non Uniformity (DSNU).
A selectable integration time and
capacitor allow for ne tuning the
conversion gain in ight. You can choose
from High Sensitivity (HS) mode and
High Dynamic Range (HDR) mode.
Furthermore the high maximum line rate
of 10 kHz enables a high resolution in
the time domain.
