SWIR Vision Systems is a provider of CQD (colloidal quantum-dot-based) short wavelength infrared (SWIR) technology – a technology that extends the detectable light spectrum to see through objects and capture images that were not previously possible.
The integration of this patented technology within onsemi’s CMOS sensors will help to significantly enhance its intelligent sensing product portfolio and pave the way for further growth in key markets such as industrial, automotive and defence.
CQD uses nanoparticles or crystals with unique optical and electronic properties that can be precisely tuned to absorb an extended wavelength of light. This technology extends the visibility and detection of systems beyond the range of standard CMOS sensors to SWIR wavelengths.
To date, SWIR technology has been limited in adoption due to the high cost and manufacturing complexity of the traditional indium gallium arsenide (InGAas) process. With this acquisition, onsemi said that it will combine its silicon-based CMOS sensors and manufacturing expertise with the CQD technology to deliver highly integrated SWIR sensors at lower cost and higher volume. Consequently, it will be possible to deliver more compact, cost-effective imaging systems that can offer extended spectrum and be used in a wide array of applications.
These advanced SWIR sensors can see through dense materials, gases, fabrics and plastics, which is essential across many industries, particularly for industrial applications such as surveillance systems, silicon inspection, machine vision imaging and food inspection. In autonomous vehicle imaging, the higher spectra will create better visibility to see through difficult conditions such as extreme darkness, thick fog or winter glare.
SWIR Vision Systems is now a wholly owned subsidiary of onsemi. While the company will be integrated into onsemi’s Intelligent Sensing Group the team will continue to operate in North Carolina.
