Emberion VS20 CL camera core offers a full camera functionality with implementations for sensor readout and control, analog-to-digital signal conversion, calibration, image pre-processing, thermal control, power management and standard digital camera interface. A stable performance over a wide environmental temperature range is ensured with a thermoelectric cooling (TEC) element built in the image sensor package. The camera core circuit boards can be built into a stand-alone housed camera or integrated into a hosting imaging system. The module boards can be positioned in various ways due to the flexible connectors between the boards. Potential applications of the image sensor and camera lie in multiple domains, e.g. monochromatic machine vision and multispectral and hyperspectral imaging.
Emberion VS20 Camera Core with Camera link is available now for custom request and will support Camera Link (Emberion VS20 CL) interface.
In future camera core with GigE Vision interface will be available (Emberion VS20 GigE Camera Core).
Emberion VS20 CL camera core (CC) 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.

B: Swir Image of semiconductor wafer : SWIR allows see through wafer cabability for inspection and alignment
Defence & Surveillance: Adverse Weather
A: Emberion VS20 Image (no filter): broadband image
B: SWIR image with backlight demonstrating see through smoke for adverse condition: surveillance application.
(Note: Long pass filter >1000nm used for SWIR imaging only)
- SWIR can offer better contrast than VIS: camouflaged targets
- Target recognition based on spectral finger prints
- Covert active imaging with SWIR light >1500 nm
- Temporal and spatial alignment of VIS and SWIR image information: head-worn vision systems (system complexity, user experience)
- Better light transmission, enhanced vision in limited visibility conditions: smoke, dust, fog, haze & low-light
Food and Pharmaceutical Industry Packaging
A: Visible Image (Visual features dominate)
B: SWIR image seeing through the opaque package.
IR image shows the vials very clearly underneath the opaque package. Some of the printed package labels are not visible in IR light. However, the printings on the left-most vial are visible. The fill-up level of the transparent liquid in the vial is very visible due to the water’s high light absorption factor at 1550 nm

Counterfeit & Security
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).
