2 Introducing Quantum Dots for short-wave IR imaging! Acuros TM CQD TM films turn silicon ICs into infrared sensors Encapsulant CQD film layer Pixels Silicon CQD TM thin film coating on silicon ICs Very low cost materials & processing Uses low cost off-the-shelf silicon as substrate Very high pixel density for highest resolution Quantum dots are already commercialized for Flat Panel TVs Now for the first time SWIR Vision Systems introduces Quantum Dots for SWIR cameras 2

3 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 Consumer Electronics Industrial Inspection Security, Surveillance 3

4 but new solutions are needed in short wave IR Limitations with existing solutions: Silicon sensors stop working in the near-ir InGaAs technology has limited resolution InGaAs technology is expensive The Acuros CQD camera overcomes these limits 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 4
