Linescan cameras benefit from extended sensitivity
The new DALSA Piranha ES (Extended Sensitivity) linescan cameras with Time Delay & Integration (TDI) deliver an impressive combination of speed, resolution and sensitivity in low-light applications. Available in Europe through Stemmer Imaging, the ES series bridges the sensitivity gap between single-line cameras and the highest-sensitivity Piranha HS series. With up to 32 TDI stages and up to 8k resolution, the Piranha ES cameras are said to create new opportunities for high-performance, cost-sensitive inspection.
The Piranha ES series offers up to 30 times more responsivity than traditional linescan cameras with up to 110kHz line rate (4k80). Configurable Base or Medium (4k) or Medium or Full (8k) Camera Link interfaces are available. An area mode of operation facilitates camera set-up by allowing the possibility of focusing on a larger imaging area that can also be used as a regular mode of operation. Other programmable features include the number of taps, bit depth, flat field correction, direction control, stage selectability, and gain and offset control.
Stemmer Imaging says the new TDI family makes it easy and cost-effective to switch from linescan to TDI. The cameras provide the line rates and responsivity necessary for high-performance applications and enable the number of cameras in the system to be reduced. Fewer cameras means fewer framegrabbers, lenses, computers and cables. The Piranha ES family is said to be the lowest price/pixel TDI system ever offered by DALSA. Lighting costs can also be reduced, since TDI imaging permits the use of LED lights.
