Color Fidelity in new 3CCD Color Cameras

Jai announces the AT-140CL and the AT-200CL, the latest generation in its 3CCD color camera series. The new 3-by-1.4-megapixel and 3-by-2-megapixel cameras draw upon Jai's expertise in prism-block technology to provide a larger sensor format and higher resolution than previously available 3CCD RGB models.

The CCDs are affixed to a newly-developed prism block that splits the incoming light into red, green, and blue color channels. Jai's patented alignment process ensures the three sensors are aligned to within 1/4-pixel accuracy, providing pixel-precise color values suitable for machine vision analysis, measurement, and processing.

The AT-140CL features three 1/2-inch progressive scan CCDs (Sony ICX267AL), each with a resolution of 1,392 x 1,040 pixels and an individual pixel size of 4.65 by 4.65 microns. The AT-200CL uses three 1/1.8-inch progressive scan CCDs (Sony ICX274AL) to provide a resolution of 1,628 x 1,236 pixels with an individual pixel size of 4.4 microns square. The data's output occurs via digital Camera Link Interface. Currently, Jai is developing versions with GigE Vision interfaces.

Significantly faster frame rates than the base rates can be achieved via the cameras' partial scan and vertical binning modes. Partial scanning includes four preset modes with frame rates in excess of 70 fps for 1/8 partial scan, as well as a user programmable mode with scan heights ranging from a single line to a full frame.
