Point Grey, a manufacturer of high-performance digital cameras, has added a 2.3 megapixel global shutter CMOS model to its Grasshopper3 family of USB3 Vision cameras.
The Grasshopper3 GS3-U3-23S6M-C model uses Sony's monochrome IMX174 global shutter CMOS sensor for the machine vision market. The sensitive IMX174 Exmor CMOS offers an image resolution of 1,920 x 1,200 pixels and frame rates up to 162fps. The sensor also supports many features required for industrial and scientific applications, such as high-speed triggering and region of interest (ROI) functionality. The ROI feature allows users to select smaller HD 1080p or 720p image sizes that run at faster frame rates.
To achieve optimal imaging performance, Sony’s analogue memory stores and shields the light collected in the photodiode. This technology minimises common global shutter CMOS artefacts such as fixed pattern noise and dramatically lowers read noise levels to 7 electrons.
The GS3-U3-23C6M-C is available to order now and a colour version (GS3-U3-23C6C-C) is expected to be released later this year.
