Pipe & Tube Inner Wall Inspection Lens For Metal Tubes and Fluid Passages
Pipe and Tube Inner Wall Inspection Lens for Metal Tubes and Fluid Passages
Blog, Company News, Customized Lens Introduction
Introduction Inspecting the outside of a metal tube is relatively easy. However, defects inside a pipe, fluid passage, or narrow internal channel are much harder to find. Scratches, burrs, corrosion, contamination, metal chips, machining marks, and foreign objects may remain inside the part even when the external surface looks normal. For many industrial components, these hidden defects can affect flow, sealing, cleanliness, assembly quality, and product reliability. Because of this, manufacturers often need an optical solution that can look directly at the inner wall of tubes, pipes, bores, and fluid passages. A standard machine vision lens usually works well for external inspection. However, it may not provide enough access or viewing angle for narrow internal…

Mid-Autumn Festival Holiday Notice 2026 from VY Optics
Blog, Company News
If you work in optics, you see a lot of circles every day. Lenses are round. Lens barrels are round. Many laser spots are round. And during the Mid-Autumn Festival, there is one more circle that matters in China: the full moon. The Mid-Autumn Festival is one of the traditional holidays in China. It is a time for families to get together, share mooncakes, and enjoy the full moon. This year, VY Optics will also take a short break for the holiday. Our Mid-Autumn Festival Holiday Schedule Holiday: September 25–27, 2026 Normal work will resume on September 28, 2026. During the holiday, replies to emails, technical discussions, quotations, and order processing may be a little…

inner wall inspection lens for automotive parts fuel injectors brake lines and valve bodies by VY Optics
Inner Wall Inspection Lens for Automotive Parts: Fuel Injectors, Brake Lines and Valve Bodies
Aerospace, Artificial Intelligence, Blog, Company News, Eight Environmental Monitoring
Introduction Automotive parts often have internal structures that are difficult to inspect from the outside. A fuel injector, brake line, valve body, cooling channel, or precision machined part may look fine on the surface. However, scratches, burrs, pits, contamination, metal chips, or machining marks can still remain inside narrow holes and internal passages. These internal defects may affect flow, sealing, cleanliness, assembly quality, and long-term reliability. Because of this, many automotive component manufacturers need a practical way to inspect the inner wall of small holes, tubes, bores, and cavities. A standard machine vision lens may work well for external surfaces. However, it usually cannot enter or observe narrow internal areas properly. This is where an…

Inner Wall Inspection Lens for Hydraulic Valve Bores
Inner Wall Inspection Lens for Hydraulic Valve Bores and Deep-Bore Components
Blog, Company News, Customized Lens Introduction, Customized Optical Solutions
Introduction Hydraulic valve bores and deep-bore components are not always easy to inspect. From the outside, the part may look clean and well machined. However, scratches, burrs, pits, contamination, and machining marks can still remain on the inner wall. For hydraulic components, these small internal defects may affect sealing, flow stability, assembly quality, and long-term reliability. Because of this, many manufacturers need a practical way to inspect the inner wall of bores, sleeves, bushings, cylinder blocks, and other deep-hole parts. A standard machine vision lens is often not enough for this type of inspection. The lens must enter a narrow space, work with limited lighting, and still provide a useful view of the internal wall.…

how to choose an inner wall inspection lens for deep holes and pipes by VY Optics
How to Choose an Inner Wall Inspection Lens for Deep Holes and Pipes
Blog, Company News
Introduction Choosing a lens for inner wall inspection is not the same as choosing a standard machine vision lens. For normal surface inspection, the camera and lens usually look at the outside of a part. The space is open, the lighting is easier to arrange, and the working distance is usually clear. However, deep-hole and pipe inspection are different. The lens may need to enter a narrow hole, look inside a curved wall, work with limited lighting, and still show defects clearly. Scratches, cracks, burrs, pits, contamination, corrosion, and machining marks may appear inside areas that are hard to reach. Because of this, the lens must match the real inspection condition, not only the camera…

VY-0430 Inner Wall Inspection Lens for Deep Holes and Pipes | VY Optics
Blog, Company News
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 has a front-end outer diameter of approximately Φ8.4 mm, a…

custom AOI optical lens design from requirement to final assembly by VY Optics
Custom AOI Optical Lens Design: From Requirement to Final Assembly
Blog, Company News
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…

Low-Distortion Lens Selection Guide for AOI and Industrial Inspection
Artificial Intelligence, Autonomous Driving, Blog, Company News, Customized Optical Solutions
Low-Distortion Lens Selection Guide for AOI and Industrial Inspection Introduction When customers choose a lens for AOI or industrial inspection equipment, they often start with focal length, working distance, and camera resolution. These parameters are important, but they do not fully answer one key question: Can the lens keep the image geometry stable enough for reliable inspection? In many AOI systems, the image may look clear, but the measurement result is still unstable. A line may appear slightly curved near the edge. A hole may measure differently in different areas of the image. A connector pin may look shifted even when the part itself is correct. In these situations, lens distortion may be one of…
