Due to the large size of the object, achieving uniform light intensity and resolution across the entire surface is challenging, requiring multiple images. When using a fixed focal lens, the light intensity is consistent, but the angle of view causes the sides of the fins to be visible at the edges.

The integration of custom lighting and a wide-field telecentric lens enables the capture of images with fewer imaging cycles, significantly reducing inspection time. This setup ensures uniform light intensity in the images, providing consistent visibility of the fins from the center to the edges.
