UV adhesive on glass: inspect the visible bead path
Under 365 nm illumination, the source capture shows a bright adhesive path against a dark field. The useful trial is to separate bead shape and visible gaps from the strength or cure state of the bond.
Use fluorescence contrast to inspect the bead shape, then validate the bond by the required method.

What the camera saw
Cropped from the source test sheet; original test annotations are retained. Captures are not generated or enhanced. Drag a comparison slider, or open any image full size.
The challenge
Transparent glass and clear adhesive can have little contrast under visible illumination.
A bright bead may still contain variation in thickness, fluorescence response or cure state.
How it was solved
The source identifies 365 nm UV ring illumination and captions the capture as adhesive-break inspection on glass.
The current LS-RS7430-UV365 is a proposed alternative, not the source version. Confirm excitation response and a suitable camera-side emission filter on the actual adhesive.
Why it works
- 1
UV excitation can produce visible fluorescence in compatible adhesives; the source capture shows bright contrast under UV illumination.
- 2
Visible continuity is an appearance property. The capture contains no bond-strength, cure-depth or leak-test result.
Lighting application-lab catalog capture
Evidence you can inspect
The bead path and two internal adhesive marks appear brighter than their surroundings.
The source reports a 365 nm UV lighting arrangement for glass adhesive-break inspection, without bead dimensions or quantified detection results.
A single source image. It does not establish UV response for another adhesive formulation or guarantee that every visible gap is a failed bond.
From image contrast to a production decision
What to validate on your part
- 01
Test the exact adhesive
Include substrate, glue formulation, batch, cure condition and contamination variation.
- 02
Challenge the bead
Use labelled gaps and excess/insufficient material near the acceptance limit.
- 03
Separate optical and bond tests
Validate image decisions independently of the required strength, cure or leak acceptance.

"Tested" identifies the part named in the source. "Our pick" is a proposed alternative or supporting part. Confirm colour, optics, controllers, power supplies, cables and mounting before ordering.
The set-up
| Lighting | 365 nm UV excitation |
|---|---|
| Source recipe | Different ring version; current ring is proposed |
| Proposed ring envelope | 74 mm OD × 40 mm aperture × 20 mm high |
| Camera and lens | Source versions not identified; current proposed parts below |
| 3D spacing | Illustrative, to be confirmed on the sample |
| Derived proposed field | 84.456 × 70.656 mm = sensor dimensions / 0.1x; source field not supplied |
| Mounting (proposed) | LS-BT-XZ-G-6-6045; 600 mm column, 600 × 450 mm base, glass tray and two light holders |
Mount the optics with intent
The station is an optical test bench, with its two lighting holders included in the catalog listing. The 3D column and base follow the published height and footprint. Carriages, clamps and part supports are schematic: confirm camera screw pattern, lens support, light fasteners, permissible load and actual travel before ordering.
Complete the electrical system
Select a controller against the exact light voltage, drive mode and power, then confirm camera data/power/I/O cables and a suitable PC. These are not silently added to the proposed optical kit.
Build this system
Start from this setup, adapt it to your part.
The configurator opens with this study's camera, lens, light and station picked. Swap any part, check fit and price, then buy or ask for a quote.
Camera and available lens CAD are published models. Lens and light envelopes use printed dimensions. The linked station uses its published base size and column height; carriage, brackets, fittings, parts and spacing are illustrative. Confirm load, travel, fasteners and clearances before ordering. Light paths explain the arrangement and do not simulate optical performance. The illustrated ring position keeps the drawn viewing envelope inside its central aperture; verify vignetting and illumination on the actual sample. Representative part geometry is illustrative, not reconstructed inspection evidence.

About this case study: the photos and camera images come from the application laboratory of the maker of the lighting and optics we sell, imaged on the parts shown; your results depend on your part, camera and set-up. This is an application-lab study, not a LumaSpec customer deployment. Source figures are reported results; proposed components require a fresh trial. The 3D scene illustrates the arrangement and does not simulate imaging performance.
