A 6MP global shutter CCD camera has been released by Point Grey, expanding its Grasshopper3 family of USB3 Vision cameras. The GS3-U3-60QS6 is based on colour and monochrome versions of the Sony ICX694, which is a 1" EXview HAD CCD II sensor capable of streaming 2736x2192 resolution images at 25fps.

Utilising Sony’s proprietary microlens design, the sensor improves quantum efficiency and increases IR sensitivity. Increasing the output frame rate, the ICX694’s quad-tap architecture divides the sensor into four quadrants, enabling each quadrant to be read out simultaneously. Compared to the existing GS3-U3-60S6 dual-tap model, the quad-tap GS3-U3-60QS6 model offers nearly double the frame rate. This makes the CCD camera suitable for biometrics, such as eye tracking and iris recognition; factory automation, such as flat panel display inspection; 2D and 3D metrology and life sciences.

For optimal performance and reliability, the Grasshopper3 utilises a proprietary USB 3.0 link layer and frame buffer-based architecture. To enable colour interpolation, look up table, gamma correction, pixel binning and USB3 Vision support, the Grasshopper3 uses an advanced image processing pipeline.

"This latest 6.0 MP Grasshopper3 model demonstrates the full capability of USB 3.0 and the incredible imaging of Sony multi-tap CCDs,” said Michael Gibbons, Director of Sales and Marketing, Point Grey. “This powerful combination of technologies enables users to significantly reduce costs and host system hardware requirements without sacrificing performance, particularly when compared to existing dual-GigE or Base Camera Link solutions. The bandwidth capability of USB 3.0 is perfectly suited for this camera, enabling full resolution and RGB colour output at high frame rates.”

The GS3-U3-60QS6 is available now and priced at $2,795/€2,095.
