Compact collimated backlight for precision diameter and profile measurement
LXV-HFT6252-W uses a precise optical path in a compact 72 × 82 × 80 mm housing to produce white output close to parallel light. It supports high-precision silhouette measurement of metal, glass and ceramic cylinders and can be combined with coaxial or other lights when smooth-plane scratches also require reflected contrast.

Metal-cylinder profile measurement
Backlight the cylinder to measure its outer contour without direct surface reflections.
Glass-bottle diameter measurement
Use the near-parallel field to stabilise the apparent bottle boundary across the selected spacing.
Ceramic-column diameter measurement
Measure the silhouette of an opaque ceramic column against the white field.
Smooth-plane scratch inspection
Combine the collimated source with coaxial, backlight or other illumination when small scratches require a second reflected-light contrast channel.
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.
- Precise optical path
- The internal design controls output direction rather than emitting a broad diffuse field.
- Near-parallel output
- A narrower illumination-angle range supports sharper profile boundaries for measurement.
- Compact reliable structure
- The optical assembly is packaged in a 72 × 82 × 80 mm body for constrained stations.
- Combination lighting
- The source can operate with coaxial or other lights when one image must separate profile and surface information.
- Low documented load
- The single white configuration is rated 24 V / 3.6 W.
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
Define the measurement tolerance
Set the allowed diameter/profile error and required smallest edge change.
- 2
Validate the optical field
Confirm the complete silhouette fits the near-parallel illuminated region.
- 3
Control target spacing
Test expected part-position and diameter variation at the final camera geometry.
- 4
Add reflected light only if needed
Use coaxial or another source when scratches cannot be judged from silhouette alone.
- 5
Approve metrology repeatability
Calibrate and verify multiple accepted and rejected samples at production speed.

Release the exact product drawing with the complete inspection station
Dimensions, openings, mounting, channels and thermal clearances belong to the selected product only.
- 01
Reserve the complete 72 × 82 × 80 mm housing and keep the output aperture unobstructed.
- 02
Align the backlight, cylinder axis and camera measurement plane to minimise perspective and edge-threshold shift.
- 03
Fix the validated target-to-light spacing and prevent moving fixtures from entering the collimated path.
- 04
Use mounting-hole, aperture, cable and connector coordinates only from the exact LXV-HFT6252-W drawing; no PDF detail module is available.
- 05
Provide 24 V / 3.6 W capacity and coordinate trigger timing with any coaxial or secondary illumination.
- 06
Validate profile sharpness, diameter repeatability, secondary-light cross-talk and housing temperature before release.
