Key Features of the Adjustable Focus Inspection Lens
Adjustable Focus for Flexible Inspection
The adjustable focus function helps users bring internal surfaces into focus under suitable inspection conditions. Therefore, the lens can support inspection setups where the object distance or component dimensions vary within its designed operating range.
Designed for Internal Surface Imaging
The optical configuration is intended for viewing surfaces inside tubes, bores, and cylindrical parts. The actual visible area depends on the lens design, bore geometry, illumination, and camera position.
Applications of an Inner Wall Inspection Lens
- Tube inspection: Imaging the internal surfaces of compatible tubes.
- Bore inspection: Visual inspection of internal cylindrical surfaces.
- Machined component inspection: Imaging internal features in suitable manufactured parts.
- Industrial quality inspection: Evaluating visible internal surface conditions.
How to Choose the Right Inner Wall Inspection Lens
- Minimum internal diameter of the tube or bore.
- Required working distance and focus adjustment range.
- Desired field of view and image coverage.
- Camera sensor size, resolution, and mounting interface.
- Illumination conditions and surface reflectivity.
- Available installation space and lens dimensions.
