JAI developed the AT-030MCL as an addition to the popular 3 CCD area scan cameras AT-140 and AT-200 with resolutions of 1.4 or 2.0 Megapixels. Equipped with three ICX424AL CCD sensors delivering 659 (h) x 494 (v) pixels of resolution per channel with an individual pixel size of 7.4 by 7.4 4 µm, and the high frame rates of up to 120 frames per second the AT-030MCL offers a combination of high speed, VGA resolution, and low price point. With the use of partial scan and binning modes the camera can be set to operate at significantly higher frame rates. For example, with 1/8 partial scan, the camera delivers 659 (h) x 60(v) pixels at 422 frames/second.
The AT-030MCL camera – featuring a Mini CameraLink interface – is equipped with JAI’s advanced prism-block technology supporting three 1/3 inch CCDs mounted on a special prism, capturing a specific red, green and blue colour value for each pixel. In this way the AT series provide a very precise colour output and a better spatial resolution than the cameras based on the conventional Bayer colour interpolation techniques.
AT-030MCL’s Dual?CameraLink interface lets users choose between 8, 10 or 12 bit output per channel allowing a full 36 bit RGB colour output. A CameraLink base or medium configuration can be used, as required.
A variety of features are provided to optimise image quality for specific applications and lighting conditions. Included are four white balance modes, three gamma settings plus a Look-Up Table (LUT).
AT-030MCL fills a gap in the market for high-speed machine vision sorting or inspection where there is a requirement to detect the most subtle colour variations on the inspected items - pharmaceutical inspection being a good example. This makes the AT-030MCL particularly well-suited to the pharmaceutical industry where there is a need for high precision inspection of tablets and ampoules. Among the popular applications are colour verification of mixed powders and integrity and precise colour check of coatings on pills/tablets. Besides pharmaceutical applications, the AT-030MCL is also relevant in food sorting, print inspection, LED diode inspection, PCB inspection and other high speed inspection applications, where there is a need to reject items with even very subtle colour variations.
