Digital, High Speed, InGaAs Photodiode Arrays Up To 2.6 µm: LC / LSC Series Datasheet

The LC/LSC Series of InGaAs linear arrays are offered in configurations with 256, 512, and 1024 elements, featuring pixel pitches of 25µm or 50µm, and pixel heights of 25 µm, 250 µm, and 500 µm. These 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, and extended ranges of 1.1 to 2.2 μm and 1.1 to 2.6 μm. Anti-blooming protection prevents charge flow from saturated pixels, allowing for increased dynamic range and image fidelity. An autozero function reduces dark current and non-uniformity, thereby extending the detector’s operational range to higher temperatures and longer exposure times.

These photodetector arrays are hybridized with Sensor Unlimited Inc.’s (SUI) proprietary CMOS readout- integrated circuits (ROICs), ensuring maximum noise immunity and sensitivity. Optimal ROIC performance requires minimal circuitry, needing only one analog supply and three digital control lines. Four separate gains are selectable with a serial input.

The arrays, renowned for their durability and reliability are available with either a one- or two-stage thermoelectric cooler for temperature stabilization and monitoring.
