VY-0430 Inner Wall Inspection Lens for Deep Holes and Pipes Introduction VY Optics is pleased to introduce the VY-0430 Inner Wall Inspection Lens for deep holes, pipes, bores, tubes, and precision internal cavities. Inner wall inspection is a common need in many industries. However, it is not always easy to do well. Usually, the outside of a part is easy to see. By contrast, the inside wall of a hole, tube, or cavity is much harder to inspect. Scratches, cracks, burrs, pits, contamination, corrosion, and machining marks may appear in places where a standard lens cannot reach. Because of this, VY Optics developed the VY-0430 as a compact wide-angle lens for internal wall inspection. This lens…

Custom AOI Optical Lens Design: From Requirement to Final Assembly Introduction In many AOI projects, customers first ask for a lens with a certain focal length, working distance, or magnification. These details are important. However, they are only the starting point. For automated optical inspection, the final image quality depends on the whole system. The lens needs to match the camera sensor, field of view, working distance, lighting, defect size, mechanical space, and inspection target. If one part is not well matched, the system may still have problems. For example, the image may have soft edges, missed defects, unstable measurement, distortion, or repeated calibration. Therefore, custom AOI optical lens design should not start only from…

Introduction When customers select a lens for an automated optical inspection system, they often compare two options: a flat-field lens and a telecentric lens. At first, the choice may seem simple. However, these two terms describe different optical characteristics rather than two completely opposite lens types. Optical designers use a flat-field design to improve image consistency from the center to the edge of the field. By contrast, a telecentric design helps maintain a more stable magnification when the object position or height changes. Therefore, a lens can offer flat-field performance, telecentric performance, or both. The right choice depends on what the AOI system actually needs to do. For example, some systems mainly detect surface defects,…
