LE / LSE Series

InGaAs Linear Photodiode Array

The high resolution LE/LSE series linear InGaAs photodiode arrays have set the standard for high performance.

REQUEST INFORMATION SHARE

    SUI produces LE /LSE InGaAs array products with 512 and 1024 elements on a 25µm or 50µm pixel pitch with pixel heights of 250 and 500 µm. Standard wavelength range of 0.8 to 1.7 μm or extended wavelength 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
