High speed, resolution, and dynamic range imaging with true metrology in a compact design

Recent advancements in Contact Image Sensor (CIS) technology are transforming machine vision systems. With high speed, high resolution, high dynamic range, and true metrology, CIS is ideal for inspection tasks in spatially restricted environments, including battery, print, and PCB production lines.

One of the CIS advantages is its small form factor compared with conventional line scan cameras. The working distance for a CIS is typically 10~20mm from the object being inspected, as compared with 250~500mm using a conventional line scan camera-based inspection system. Inline automatic optical inspection (AOI) is now becoming an important part of a modern production line to enable real-time, high-throughput quality control. For production equipment with compact designs, only CIS can fit. CIS also offers a higher degree of integration that combines camera, lens, and lighting components and makes system designs much quicker and easier. Because of these advantages, more and more machine vision applications are adopting CIS technology.
