What inspection variables should be evaluated?
Curved-surface reflections change with rotation. Test several poses and positions near the tunnel entrance and exit.
What lighting geometry fits this inspection task?
A tunnel surrounds the scan region with diffuse illumination. Check entrance clearance, scan-line position and coverage at both ends on reflective or curved samples.
Align the illuminated line with the camera scan line and cover the complete inspection width. Compare brightness, working distance and line width together; housing length alone is not enough. Continuous motion also needs stable triggering and speed information.
Fix line rate and exposure, compare both ends with the centre, and check moving samples for smear and banding. Cooling affects sustained operation, so repeat captures after temperature stabilises. Record speed, mounting angle and controller settings to make the setup reproducible.

Before choosing a configuration?
For selection, specify the field of view, smallest target feature, height variation, cycle time and installation space. Use the specific product page and drawing to verify electrical ratings, dimensions and compatibility.
Controlling reflections from curved parts?
A tunnel arrangement surrounds more of the viewing region with light, which can soften reflected hotspots. Curvature, source openings and camera position still determine the image. Test the actual part instead of a flat substitute.
Rotate the part and move it through its height tolerance. Look for dark bands caused by openings or fixtures. Compare whether the smoother background improves the target defect without removing useful shape information.
