Emberion - Model VS20 Core GigE -VIS-SWIR Camera Core
Emberion VS20 Core GigE interface offers a unique broad-spectrum and wide dynamic range imaging performance. The camera core is unhoused and it comprises the sensor, front-end, processing and IO module boards. The VGA-resolution image sensor is based on a proprietary image sensor technology and comprises a light-absorbing Colloidal Quantum Dots (CQD) layer built monolithically on a tailor-made CMOS readout integrated circuit. The CQDs provide an extremely wide spectral response range spanning from visible (VIS) to near infrared (NIR) and up to short-wave infrared (SWIR) wavelengths. The dynamic operation range of the image sensor is very large, owing both to the low noise and non-saturating characteristics of the photodetector.
Wide, tunable spectral range covered with a single sensor array , from visible 400 nm (VIS) light to short-wave infrared 2000 nm (SWIR).
Large inherent dynamic operation range, enabling High-Dynamic-Range (HDR) imaging
Cost-efficient sensor manufacturing process, providing affordable camera solutions for a wide range of imaging applications
In house designed CMOS ROIC supporting low noise
Easy integration for various systems enabling key application areas.
HIGH DYNAMIC RANGE
High Dynamic Range – High dynamic range sensor incorporated in VS20 camera. Emberion’s HDR with 80dB performance is ideal for large variations in brightness level with a single exposure.
- Can handle large variations in irradiance level: operation in day and night conditions, better contrast
- Bright spots do not obscure neighbouring dark objects: headlights in low-light conditions
Better contrast in SWIR than in VIS light: camouflage materials designed for VIS and human eyes.
BEYOND 1700NM EXTENDED RANGE
Emberion’s camera extends beyond 1700nm compared to incumbent technologies, up to 2000nm. Applications such as PVC detection in waste recycling can be hugely beneficial using 1700nm peak for plastic sorting or detection of the strong water peak at 1920nm. This can be clearly demonstrated using the camera.
The images show that using 1920nm narrowband pass filter and halogen lamps the VS20 can be used to detect moisture absorption. It shows water is very strongly absorbed in that region and can be used for identifying water ingress , food quality, moisture in wood and paper (pulp).
