InGaAs Linear Photodiode Arrays

The LDB / LSB-series linear InGaAs photodiode arrays have set the standard for high performance in near-infrared spectroscopy and imaging applications.

REQUEST INFORMATION SHARE

    SUI produces LDB / LSB InGaAs array products with 256 and 512 elements on a 25 µm or 50 µm pixel pitch with pixel heights of 250 and 500 µm. Standard wavelength range of 0.8 to 1.7 μm, a shorter range of 0.8 to 1.45 μm or extended wavelength range of 1.1 to 2.2 μm. These channels are 100% operable and have unmatched uniformity. The photodetector arrays are hybridized with CMOS readout integrated circuits (ROIC) of SUI 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 thermoelectric coolers for temperature stabilization and monitoring. These arrays are widely used for optical performance monitoring of S, C & L band channels in DWDM networks. Other applications include agricultural sorting, biomedical analysis, thermal imaging and industrial process control.  The SUI LDB / LSB-Series photodiode arrays are telecommunication system reliable and available in volume.
