SCI640B VGA SWIR ROIC (Analog Out)

Attollo’s SCI640B Readout Integrated Circuit (ROIC) is designed for SWIR focal plane arrays with a resolution of  640 x 512 pixels with a pitch of 15 microns.

The SCI640B ROIC pixels have a Capacitive Transimpedance Amplifier (CTIA), designed for P on N polarity diodes. Very short exposure time windows with programmable start and stop can be controlled with integrate then read (ITR) or integrate while read (IWR) snapshot functionality. Groups of 2×2 pixels can also be binned to enhance sensitivity. Other ROIC operating modes include non-destructive Read (NDR) and high dynamic range (HDR) imaging.

The ROIC is well-suited for SWIR applications using detector materials such as InGaAs and CQDs.  Attollo can deposit customized metallization stacks for your application.

Available for purchase in full, half, and quarter wafers.
