Function of Inner Wall Inspection Lens

The inner wall inspection lens (also known as bore/360° inner wall lens) is a core component of machine vision and industrial endoscopes. It is specifically designed to address imaging and inspection challenges for closed cavities, deep holes, and pipe inner walls that are inaccessible to the human eye.

I. Core Functions (Three Key Capabilities) 

1. Non‑destructive Visualization (Primary)

Enables real‑time high‑definition imaging of inner walls without disassembly or damage to products, penetrating narrow/confined spaces (e.g., engine blocks, pipes, bottle caps, bearing bores) as a replacement for manual visual inspection.

2. Defect Detection (Quality Control)

Accurately identifies inner‑surface flaws: scratches, cracks, corrosion, burrs, porosity, contamination, foreign‑object blockages, and weld defects.

3. Precision Measurement (Dimensional Verification)

Measures geometric parameters such as bore diameter, roundness, depth, groove width, thread integrity, and step height when integrated with algorithms.

II. Working Principle 

360° Panoramic Imaging: Captures the full circumference of the inner wall in one shot via specialized prisms/reflective optics, eliminating blind spots.

Telecentric/Low‑Distortion Design: Ensures undistorted inner‑wall imaging for high‑precision measurement.

Large Depth of Field: Delivers clear imaging for both deep‑hole bottoms and orifices.

III. Typical Applications

Machinery Manufacturing: Inspection of bearings, gears, hydraulic cylinders, engine cylinder walls, and gun barrel inner surfaces.

Electronics/Packaging: Quality screening of bottle caps, vials, cups, and internal screw threads.

Energy/Pipelines: Inspection of corrosion/cracks in boilers, oil‑gas pipelines, and turbine blades.

Automotive Maintenance: Non‑disassembly checks for engine carbon deposits, transmission wear, and exhaust pipe blockages.

IV. Core Value

Cost‑effective & Efficient: Eliminates disassembly, drastically reducing inspection/repair time.

High Precision: Detects micron‑level defects to prevent missed inspections.

Safe & Reliable: Suitable for high‑temperature, toxic, and otherwise inaccessible hazardous environments.
