Allied vision is one of the first camera manufacturers in the world to introduce Sony’s innovative senswir InGaAs sensors. This series of sensors will be carried into the popular goldeye SWIR series, which can realize photosensitive imaging in the range of visible spectrum and short wave infrared (SWIR) spectrum at the same time.
The goldeye g-030 is equipped with Sony imx991 sensor, while the 1.3 MP goldeye g-130 is equipped with imx990 senswir sensor. Both models are equipped with GigE vision interface and built-in single-stage thermoelectric sensor cooling (TEC1). Models equipped with camera link interface are planned to be launched in the fourth quarter of 2021.
Senswir sensor technology – wider spectral range, smaller pixel size
This new sensor is developed based on Sony’s new senswir Technology: using the innovative InGaAs sensor architecture, it has achieved a qualitative leap in pixel size and image uniformity, and can realize high quantum efficiency image acquisition in the range of visible spectrum and short wave infrared spectrum (400 nm to 1700 nm). This technology compresses the pixel size to 5 µ m, which greatly expands the application space of goldeye SWIR camera in object spectral analysis and further improves the accuracy of detail detection.
Goldeye new model details
Adopted by goldeye g-030 ¼ Inch VGA sensor imx991 with a frame rate of 234 FPS at 656 x 520 pixels. The goldeye g-130 is equipped with imx990 1.3MP SXGA sensor (1280 x 1024 pixels) with a maximum frame rate of 94 FPS.
Both new models have a rugged, compact design without fans and are optimized for industrial applications. Integrated with single-stage sensor cooling (TEC1) and multiple image correction functions, the image quality is upgraded further. I / O and genicam standards are fully compatible with functional control options, which can greatly simplify the camera system integration.
● support visible light and expand the imaging spectral range (400-1700nm)
Sony senswir InGaAs sensor adopts ultra-thin indium phosphide (INP) layer structure design, allowing visible light to pass through the sensitive InGaAs layer. Although there are InGaAs sensors compatible with visible spectral range imaging on the market, Sony is the first manufacturer to successfully maintain the quantum efficiency in the full spectral range (400-1700nm) at a relatively high level (> 50%). In some application fields (such as spectral imaging and video surveillance), visible and invisible light imaging can be realized with only one camera, so this feature also helps to reduce the system cost.
● higher detection accuracy (5 µ m pixel spacing)
As low as 5 µ M can be achieved by using copper copper bond instead of indium column between indium gallium arsenic (InGaAs) photodiode layer and silicon-based readout circuit layer ² Smaller pixel size. This helps to achieve high spatial resolution imaging and reveal finer subject details.
● higher image uniformity
The integrated digital output function of Sony senswir sensor will also be applied to our goldeye series cameras for the first time. The previous generation analog sensor needs to integrate an external ADC to operate, and visible vertical stripes will be generated during imaging, so non-uniformity correction (NUC) must be carried out after imaging.
In addition, Sony uses copper copper bond to connect InGaAs layer and silicon-based readout circuit layer in its stack design, ensuring high image uniformity of senswir sensor. This design ensures a more reliable and uniform connection between the two layers than existing solutions using indium columns.
● simplified filter integration
Sony senswir sensor is relatively small in size, and SXGA sensor is even only 1 / 2 inch. The interface option of the new goldeye model can easily fit into the standard C interface filter, reducing the overall cost.
