Quadlinear camera for multispectral imaging

21 October 2014

Teledyne DALSA has introduced its Piranha4 2k quadlinear line scan camera featuring red, green, and blue (RGB) outputs plus a Near Infrared (NIR) channel for multispectral imaging.

The quadlinear Piranha4 is built around Teledyne DALSA‚Äôs CMOS image sensor design. Wafer-level dichroic filters enable spectrally independent RGB and NIR outputs, enhancing detection capability for a range of machine vision applications, such as print, bank note inspection, electronics manufacturing and material sorting. 
 
The RGB+NIR Piranha4 multispectral camera is available in 2k resolution, with 14.08 micron pixel size and delivers a maximum line rate of 70 kHz. In addition to its multispectral capability, the camera also features sub-pixel spatial correction, horizontal parallax correction, multiple AOI and ROI, and independent exposure time for each colour channel. Flat field correction can be done on each channel or as a group.
