For the computer and software to turn it into a meaningful image, it must first be digitized. This is usually accomplished by a framegrabber, an add-on circuit board that plugs into the PCI bus of most desktop computers. Therefore, a buyer should be aware of the true processing capabilities when assembling a system from individual components. Additionally, it is very important to match the framegrabber's dynamic range with that of the camera to take full advantage of the image. An 8-bit camera and framegrabber will be able to handle the bulk of a lab's imaging demands.
Cost is commensurate with performance.
Be aware, though, not all framegrabbers are compatible with all cameras or software. When assembling a system from individual components, be sure that they are all cross-compatible. Once an image is acquired, the next step is analysis. Here's where the process gets interesting. Lanes and dots are identified for precise analysis of position and density.
