Easy-To-Use, Analog 256/512 Pixels With 25/50 µm Pitch, InGaAs Photodiode Arrays: LDB / LSB Series Datasheet

The LDB/LSB Series of linear InGaAs photodiode arrays are ideal for monitoring optical performance across S, C, and L band channels in DWDM networks. They also serve in diverse applications such as agricultural sorting, biomedical analysis, thermal imaging, and industrial process control.

The LDB/LSB series are available with options of 256 and 512 elements, available on either a 25 µm or 50 µm pixel pitch, and with pixel heights of 250 µm and 500 µm. The arrays support various wavelength ranges: a standard range of 0.8 to 1.7 μm, a shorter range of 0.8 to 1.45 μm, or an extended range of 1.1 to 2.2 μm. These photodetector arrays are integrated with SUI’s proprietary CMOS readout integrated circuits (ROIC), designed to maximize noise immunity and sensitivity.

Operating these arrays requires minimal circuitry, with only one analog supply and two digital control lines needed for optimal ROIC performance. The arrays offer selectable gains through a single input. Optionally, they can be equipped with thermoelectric coolers for temperature stabilization and monitoring.
