Sony has announced the upcoming release of two short wavelength infrared (SWIR) image sensors, the IMX 990 and IMX991. Both sensors feature 5 µm pixels and SenSWIR technology that forms photodiodes on an indium gallium arsenide (InGaAs) compound semiconductor layer, that are connected via Cu-CU connection with the silicon layer which forms the readout circuit.
According to the manufacturer, this design enables high sensitivity from the visible to invisible light spectrums in the SWIR range (0.4 to 1.7 µm).
The IMX990 is a 1.34 effective MPixel sensor with 8.2 mm diagonal that can capture 8-bit full pixel images at 130 fps, 10-bit images at 120 fps, and 12-bit images at 70 fps. The IMX991 is a 0.34 effective MPixel sensor with 4.1 mm diagonal that can capture 8-bit full pixel images at 250 fps, 10-bit images at 240 fps, and 12-bit images at 130 fps.
Both sensors will be available in Ceramic LGA packages in June 2020, and in Ceramic PGA packages with built-in thermoelectric cooling devices in July 2020.
