Piranha HS 12k camera and Xcelera-HS PX8 frame grabber

Share this on social media:

Stemmer Imaging can offer the first products utilising the new HSLink machine vision connectivity interface pioneered by Dalsa. These are the new Piranha HS 12k 90kHz line scan camera and the Xcelera-HS PX8 frame grabber.

The HSLink interface has been designed in co-operation with the Camera Link 2 subcommittee to meet the needs of all machine vision applications. It carries image data, configuration data, low jitter, and real-time triggering signals over a simple network topology supporting cameras, intermediate devices and frame grabbers. It combines the key strengths of Camera Link with new features and functions. HSLink delivers scalable bandwidth in 300MByte/s steps, from 300 to 6,000MByte/s, while using globally available, off-the-shelf components.

The Piranha HS 12k high sensitivity line scan camera has a maximum line rate of 90kHz and 12,000 pixel resolution, and is capable of delivering over 1.2 Gigapixel throughput. The camera is available in 1,200 or 640Mp/s versions and all models are capable of bidirectional operation with up to 256 stages of selectability, while preventing overexposure with anti-blooming features.

The Xcelera-HS PX8 Series of frame grabbers supports the Piranha HS 12k camera and utilises the PCI Express (PCIe) platform to provide simultaneous image acquisition and transfer with little intervention from the host CPU. For machine vision OEMs, the Xcelera-HS PX8 combines the HSLink interface with onboard preprocessing functions such as shading correction and Bayer decoding. The Xcelera-HS PX8 delivers an image acquisition bandwidth of 1.8GByte/s and host transfer bandwidth of 2GByte/s over multiple-lane PCI Express implementations. The Xcelera-HS PX8 has been built within Dalsa's Trigger-to-Image Reliability technology framework to guarantee the reliability of the image acquisition system. The new frame grabbers are supported by Dalsa's Sapera Essential standard machine vision software toolkit.
