Cameras with extended IR sensitivity see through objects and materials

Acuros^® CQD^® SWIR cameras from onsemi provide high-resolution imaging and sensing capabilities across the visible, near-infrared (NIR), and SWIR spectrum. 

The global shutter cameras, intended for use in demanding industrial applications, offer the flexibility of programmable frame time, exposure time, gain modes, window modes, binning modes, and more. 

The family of Acuros cameras is available in a variety of sensor configurations:

• 6 Mpixel resolution in 2098 px x 2040 px format 
• 4.2 Mpixel resolution in 2040 px x 2040 px format 
• 2.1 Mpixel resolution in 1920 px x 1080 px format 
• 1.2 Mpixel resolution in 1280 px x 1024 px format 
• VGA resolution in 640 px x 512 px format 

onsemi also supplies Acuros SWIR laser profiling cameras for use in systems requiring direct imaging of laser sources without the use of an external lens or other optical components that can impact the beam shape or path. 

These cameras are used by laser manufacturers, producers of laser system assemblies, and laser-based manufacturing organizations. They support applications including laser beam diagnostic imaging, laser beam profiling, and laser alignment.

The onsemi Acuros cameras are based on colloidal quantum dot-based (CQD) SWIR technology, which extends the detectable light spectrum to enable devices to see through dense materials, gases, fabrics and plastics, and to capture images that were not previously possible. 

The CQD technology uses nanoparticles or crystals with unique optical and electronic properties that can be precisely tuned to absorb an extended wavelength of light. To date, adoption of SWIR technology has been limited because of the high cost and manufacturing complexity of the traditional indium gallium arsenide (InGAas) process. 

onsemi, however, has combined its silicon-based CMOS sensors and manufacturing expertise with the CQD technology to produce highly integrated SWIR sensors at lower cost in high volume.
