The Application Report discusses different illumination approaches for inspecting reflective surfaces, highlighting the challenges of achieving both homogeneous lighting and efficient imaging. specifically in connector pin inspection. The standard brightfield illumination principle relies on the law of reflection, but it can result in blurry images. A diffuser is commonly used to achieve uniform lighting, but it reduces efficiency. The Chromasens anisotropic diffuser provides a solution by delivering high illuminance and homogeneity in the scanline direction while maintaining focus in the transport direction.
