Analog, 512/1024 Pixels With 25/50 µm Pitch, InGaAs Photodiode Arrays @ 1.25k lps: LE / LSE Series Datasheet

The LE/LSE InGaAs arrays feature 512 and 1024 elements, in 25µm or 50µm pixel pitches with pixel heights of 250µm and 500µm. These arrays cover a standard wavelength range of 0.8 to 1.7 μm or an extended range of 1.1 to 2.2 μm. Anti-blooming protection prevents charge flow from saturated pixels, allowing for increased intra-scenic dynamic range. These channels are >99% operable and have unmatched uniformity. The photodetector arrays are hybridized with CMOS readout integrated circuits (ROIC) of SUI’s exclusive design to offer maximum noise immunity and sensitivity.

Operating circuit designs need only provide for one analog supply and two digital control lines for optimum ROIC performance. Two separate gains are selectable with a single input. Arrays are available with 1 or 2 stage thermoelectric coolers for temperature stabilization and monitoring. Applications include industrial process control and inspection in agricultural sorting, biomedical analysis, thermal imaging and NIR Molecular Spectroscopy.
