Previously offered with Camera Link interfaces, the 140GE and the AT-200GE 3-CCD color camera series from JAI are now available with GigE Vision serial interfaces for operation via standard Ethernet cabling and network hardware. They feature 1.4- and 2-megapixel resolution, respectively. The AT-140GE integrates three ½” progressive scan CCDs (Sony ICX267AL), each with a resolution of 1392 x 1040 pixels and an individual pixel size of 4.65 by 4.65 µm. On the other hand, the AT-200GE uses three 1/1.8-inch progressive scan CCDs (Sony ICX274AL) to provide a resolution of 1628 x 1236 pixels with an individual pixel size of 4.4 µm2. The CCDs are affixed to a prism block that splits the incoming light into red, green, and blue color channels. The company’s patented alignment process ensures the three sensors are aligned to within ¼ -pixel accuracy, providing pixel-precise color values suitable for machine vision analysis, gauging, and processing. This is in contrast to 3CCD cameras that utilize “pixel offset” methods to increase perceived on-screen resolution, while sacrificing the precision of the digital output. With their 3-CCD technology, the cameras are particularly suitable for print inspection, paint matching, medical diagnostics, or other applications where highly accurate color values are required. A sophisticated linear color matrix circuit enables precise color matching between camera data and calibrated printers, monitors, and other devices. Users can manually tune the RGB channels, or can choose from preset sRGB or Adobe RGB industry standard color space settings developed by HP, Microsoft, and Adobe. A variety of other features are provided to optimize image quality for specific applications and lighting conditions. Included are three white balance modes (manual, one-push auto, and continuous auto), three gamma settings plus a look-up table (LUT), automatic shading compensation, blemish compensation, and a knee function with individually adjustable RGB values. The AT-140GE operates at 20 frames per second with full 3 x 1.4-megapixel output while the AT-200GE operates at 15 frames per second with full resolution. Users can select 24- or 30-bit RGB output. Faster frame rates than the base rates can be achieved via the cameras’ partial scan and binning modes. Multiple trigger modes and programmable or pre-set shutter speeds as fast as 25µs, make the cameras also suitable for a wide variety of machine vision applications.
