Made possible by a newly-developed prism block capable of supporting a larger sensor format than previously, the increased resolution and light-gathering ability of the latest generation AT-140 CL and the AT-200 CL cameras provide unsurpassed colour fidelity making them the ultimate high-performance cameras.

What is unique about the AT-140 and the AT-200 CL?
JAI's process is in contrast with other 3CCD cameras that sacrifice output precision in favour of increased screen resolution.

Light reaching the prism block is split into red, green and blue colour channels. JAI's patented alignment process ensures the three sensors are aligned to within 1/4-pixel accuracy, providing pixel-precise colour values with a degree of precision necessary for applications requiring accurate anaylsis, measurement and processing.

The AT-140CL and the AT-200CL utilize 1/2" and 1/1.8” sensors, respectively.

What other features are available?
Fully featured, both cameras are the first 3CCD progressive scan cameras to offer 3 x 12-bit RGB output (36-bit total). This enables them to distinguish between the most subtle of colour variations.
The AT-140CL operates at 25 frames per second with full 3 x 1.4-megapixel output via a Camera Link digital interface. The AT-200CL operates at 20 frames per second with full resolution.

Users can select 3 x 8-bit RGB output via a single port Camera Link base configuration, or can use the cameras' dual Camera Link connectors to output 3 x 10-bit or 3 x 12-bit RGB data via a Camera Link medium configuration.

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.

Maximising image quality comes via a comprehensive array of features targetting specific applications and lighting conditions among which are:

*** are four white balance modes
*** three gamma settings plus a Look-Up Table
*** automatic shading compensation
*** blemish compensation
*** knee function available for knee-point and knee-slope settings
*** user-ability to adjust each colour channel manually or choose from industry-standard settings.
