Fast tri-linear colour linescan camera

Firstsight Vision has introduced the Piranha tri-linear colour line scan camera from Dalsa, suitable for a host of applications, including 100 percent print inspection and postal/parcel sorting etc.

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

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

The camera, which features Dalsa's own designed and manufactured sensor, more than doubles the line rate compared to existing tri- linear line scan cameras and also offers enhanced sensitivity.

The sensor eliminates artifacts associated with 3-CCD prism cameras and by placing a separate row of pixels for each colour on a single sensor die.

The advanced design reduces distance between rows to just two lines to minimise image artifacts due to synchronization associated with other tri-linear cameras.

The result is higher quality images at higher speed.

Of particular importance in the ability of the Piranha to 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 colour 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 colour at up to 80Mpixels/second, the Piranha camera is both easy to use and powerful, offering programmable gains and offsets for each colour as well as FPN and PRNU correction.
