USB3 CMOS camera provides enhanced NIR imaging

Expanding the Grasshopper3 family of high quality, high resolution USB 3.0 cameras, Point Grey has announced the addition of a 4.1MP CMOS model. Featuring improved near-infrared (NIR) response, the Grasshopper3 GS3-U3-41C6NIR uses a proprietary USB 3.0 link layer and frame buffer-based architecture for optimal performance and reliability.

The Grasshopper3 GS3-U3-41C6NIR model is based on a monochrome version of the extremely fast CMOSIS CMV4000-3E12 device, a 1" global shutter CMOS sensor featuring 5.5µm square pixels and 2048x2048 pixel resolution running at 90fps. This sensor uses a 12µm substrate layer that has increased thickness to enhance sensor response between 750 and 1000nm in the near-infrared region of the optical spectrum. Increased sensitivity in this region will benefit applications such as open road tolling in traffic systems, fruit and vegetable inspection, ophthalmology, eye tracking, or failure analysis in industrial applications.

The camera uses an advanced image processing pipeline to enable look up table, gamma correction, pixel binning and USB3 Vision support.

Michael Gibbons, Director of Sales and Marketing, Point Grey, commented: “We are excited to enable new sensor technologies designed to increase near-infrared sensitivity and address customer demand for improved performance in targeted applications. The GS3-U3-41C6NIR model provides an appealing combination of high resolution, global shutter CMOS, fast frame rate and optimised NIR response. This makes it ideal for applications such as intelligent traffic systems, which rely on infrared lighting to illuminate license plates without distracting drivers or pedestrians, or industrial applications such as printed circuit board inspection, which rely on infrared lighting to detect points of failure.”

The Grasshopper3 GS3-U3-41C6NIR USB 3.0 camera is list priced at $1,595 (USD) or €1.195 and is available to order.
