Collimated dual-rectangular backlight for precise profile inspection
LXV-2PFTB236186-W combines a shaped backlight with a parallel-film optical layer to produce a quasi-parallel white field. This reduces angular spread at the part boundary and supports cleaner, more repeatable profiles than a broad diffuse backlight when measurement accuracy is limited by edge blur.

Part-profile inspection
Create a high-contrast silhouette for outer profiles, openings and shape comparison.
Edge-position measurement
Use the narrower ray-angle distribution to reduce boundary shift caused by target-to-panel spacing.
Dimensional inspection
Pair the collimated field with calibrated optics when stable threshold location is required.
Shaped-field fixtures
Use the dual-rectangular format when the target, nest or access path cannot use one uninterrupted illuminated panel.
How the optical structure solves the inspection problem
Review the product-specific optical behavior, confirmed values and technical graphics together before selecting the final configuration.
- Parallel-film layer
- The backlight is matched with a parallel film instead of relying on diffusion alone.
- Quasi-parallel field
- The optical stack narrows the range of illumination angles reaching the target.
- Reduced edge blur
- Lower angular spread can make the observed silhouette less sensitive to small target height changes.
- White output
- The documented white configuration supports broad camera response and neutral profile contrast.
- Model-specific thermal load
- The 37.4 W panel requires production-duty heat and uniformity validation.
Select from the actual optical, mechanical and electrical requirement
Do not select a custom light from appearance alone. Confirm target, contrast, field, interfaces and load together.
- 1
Set the measurement tolerance
Define the maximum acceptable edge-position variation and smallest profile feature.
- 2
Compare diffuse and collimated fields
Test whether quasi-parallel output materially reduces edge blur on the real part.
- 3
Confirm field and clearance
Fit the target and fixture within the shaped field and 250 × 200 × 23 mm body envelope.
- 4
Match lens and calibration
Use compatible imaging optics and calibrate at the final working geometry.
- 5
Validate production repeatability
Measure representative parts across position, height and cycle variation before release.
