Tri-linear color linescan camera launched

The Piranha tri-linear color line scan camera from Dalsa has been added to Firstsight Vision’s range of linescan cameras. 

The Piranha camera is suitable for a host of applications, including 100% print inspection, postal/parcel sorting, high performance document scanning/image lift, and high-end industrial inspection.

This new camera, which features Dalsa’s own designed and manufactured sensor, is claimed to more than double the line rate compared to existing tri- linear line scan cameras and also offers ‘enhanced sensitivity’, according to a statement.

The new sensor eliminates artifacts associated with 3-CCD prism cameras and by placing a separate row of pixels for each color on a single sensor die. The advanced design reduces distance between rows to just two lines to minimize image artifacts due to synchronization associated with other tri-linear cameras. The result is ‘higher quality images at higher speed’.

The Piranha can be used in off-axis inspection applications for the inspection of free-moving objects and use where there is non-uniform illumination.

In addition, the new camera features pigment photoresist technology for the color filters to prolong the lifetime of the sensor. Pigment photoresist is more immune to UV degradation than dye photoresist systems, giving better and longer imaging reliability and less maintenance.

With a single power supply and Camera Link interface the camera can deliver 8 or 12 bits per channel color at up to 80Mpixels/second, the Piranha camera is both easy to use and powerful, offering programmable gains and offsets for each color as well as FPN and PRNU correction.
