Introducing Quantum Dots for short-wave IR imaging!

Quantum dots are already commercialized for Flat Panel TVs

Now for the first time…

SWIR Vision Systems introduces Quantum Dots for SWIR cameras

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
