VIS-SWIR Broad Spectral Range Camera
Emberion’s first cameras product is available for deployment, which is the VS20 visible-SWIR broad spectral range camera with unique nanomaterial (quantum dot) stack based sensor solution that has been in-house designed with its own CMOS ROICs and monolithically integrated with the engineered photosensitive layers that produces a wide spectral range from 400 to 2000nm. The sensor was further developed with associated electronics and an entire image pipeline algorithm and user interface to create a camera for the machine vision industry. Image 2 is taken by the VIS-SWIR camera and demonstrates that it can see through smoke generated by fire compared to the visible image which blocks the scene with its heavy smoke.
Outlook
An additional variant will be released during Vision 2022. The new VS20 camera has a High Dynamic Range (up to 120dB) with up to 400fps. The GigE compatibility (Full VGA) camera has a monolithic integration for ease of manufacturing and scale up of manufacturing processes. Particular for applications include water peak detection at 1920nm which has the maximum contrast levels, and PVC detection beyond 1700nm in waste recycling; the camera is perfect due to the extended range of the sensors. The sensors have high pixel operability (>99.98%). The images enable detection of both bright and dark objects and allows for multispectral imaging and enabling hyperspectral solutions. The QDs can be customised to tune the wavelength peak targeting specific application domain. Emberion has a dense roadmap where it will focus on offering megapixel VIS-SWIR cameras. The QD technology has created a wide spectral range of cameras with the possibility to enhance it towards MWIR (3-5µm) and combining all the bands will be the ultimate solution for sensor fusion enabling new vision applications.
