Scheimpflug adjustment for telecentric lens
WebBecause telecentric lenses act as if they have an infinite focal length, magnification is independent of object distance. Although objects moved closer or further from the lens may vary in focus, the image size of the object will be constant. FIGURE 2. Telecentricity is measured by the chief ray or telecentric angle. WebAs an important defect detection technology, automated optical inspection (AOI) is widely used in the quality control of printed circuit board assembly (PCBA) and precision …
