Silicon sensors rule the visible imaging world…
Low cost silicon sensor chips have become ubiquitous imaging devices
► Visible & ‘Near Infrared’ imaging
► Fabricated at very large scale
► Mature, high yield processing
► Billions of units sold globally
Mobile Electronics Industrial Inspection Security, SurveillanceConsumer Electronics

SWIR users need to…
► See very small defects in industrial parts
► Inspect silicon wafers and solar cells
► See through plastics
► Detect moisture, chemicals
► Monitor objects in higher resolution
► Conduct hyperspectral imaging
► See through mist and smoke
Limitations with existing solutions:
► Silicon sensors stop working in the near-IR
► InGaAs technology has limited resolution
► InGaAs technology is expensive
…but new solutions are needed in short wave IR
The Acuros CQD camera overcomes these limits
