The pco.pixelfly 1.3 SWIR [Peak QE ≈ 90%] and SWIR1300KMA [Peak QE ≈ 75%] are TE-cooled InGaAs SWIR camera based on Sony’s SenSWIR technology. These cameras can capture images in the visible and invisible (SWIR: Short-Wavelength Infrared) regions of the spectrum. Offered in both enhanced QE [Peak QE ≈ 90%] and standard QE [Peak QE ≈ 75%] versions, these cameras have 1280 x 1024 x 5μm pixels enabling the acquisition of high-resolution VIS & SWIR images using readily-available and cost-effective ½” C-mount optics at high frame rates. These cameras operate in Global Shutter mode: all pixels begin and end exposure at the same instant – ideal for imaging fast changes or rapid motion in the Field-of-View.
The compact 1/2″ optical format of these 1.3MPix imagers is made possible by its 5μm pixel size, as compared to most SWIR imagers that have much larger pixels.
These camera are based on Sony’s proprietary SenSWIR technology, in which photodiodes are formed on an indium gallium arsenide (InGaAs) compound semiconductor layer and are connected via Cu-Cu connection with the silicon (Si) layer which forms the readout circuit — a design which enables high-sensitivity over a broad range of wavelengths. This breakthrough yields a SWIR image sensor that is compact yet capable of delivering seamless image capture over a broad range of wavelengths covering from the visible to invisible light spectrum in the short-wavelength infrared range (wavelength range: 400nm to 1700nm).
