Stemmer Releases Dalsa Piranha ES Linescan Cameras


Stemmer Imaging's Dalsa Piranha ES (Extended Sensitivity) linescan cameras feature time delay and integration (TDI). The cameras combine speed, resolution and sensitivity to low-light applications. 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 open new possibilities for high-performance cost-sensitive inspection.

The Piranha ES series is up to 30-times more responsive 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, which can also be used as a regular mode of operation.

Other programmable features include number of taps, bit depth, flat-field correction, direction control, stage selectability, and gain and offset control. The new TDI range makes it easy and cost effective to switch from line scan to TDI. The cameras provide the line rates and necessary response for high-performance applications and allow the number of cameras in the system to be reduced. Fewer cameras means fewer frame grabbers, lenses, computers and cables. The Piranha ES range also reduces lighting costs as TDI imaging allows the use of LED lights.
