Second-generation tunnel illumination for fast curved and reflective surface inspection
LXV-2SDL is a fan-cooled second-generation tunnel line-scan light with good parallelism and high luminance in a lighter housing. The PDF states approximately twice the brightness of the earlier SDL series and 50% lower weight, and positions it for cigarette packages, curved surfaces, PCB printing, vacuum packaging, metal and glossy glass inspection.

Cigarette-package surfaces
Surround the moving package with tunnel illumination for curved-surface inspection.
PCB printing and characters
Raise character contrast when exposure time is limited.
Reflective touch panels
The refrigerator-panel example shows clear characters with reflected-light interference removed.
Vacuum packs, metal and glossy glass
Use distributed tunnel illumination to control specular surface response.
Complete optical curves, brightness comparison and reflective-panel result
The technical modules retain their reference model, chart titles, axes and scales. The source comparison then connects the stated two-times brightness increase to the character and touch-panel imaging examples.

Size the tunnel, emitting length and high-power controller from the target
The seven PDF rows run from LXV-2SDL100 to LXV-2SDL1000. Each keeps its own voltage, power, weight and drawing reference; models 100–400 use 24 V, while 500–1000 use 48 V.
- 1
Measure target width and curvature
Choose a tunnel that surrounds the required imaging region.
- 2
Select length
Use the matching 100–1000 mm row.
- 3
Confirm exposure speed
Validate the source brightness advantage at production line rate.
- 4
Plan fan and controller capacity
Provide airflow and match the 24/48 V power row.

Keep the full tunnel opening, fans and connector envelope unobstructed
The source offers general use and combination with a coaxial line light. Both dimension groups are preserved without splitting a complete housing drawing.
- Centre the workpiece path through the tunnel opening.
- Keep all fan inlets and outlets clear.
- Reserve connector and controller cable routes.
- Use the exact dimension group for the selected model.
