Application study · Glass bondingUV 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.

Proposed component
MV-CS050-10GC
5 MP colour global-shutter camera for colour and angle-coded contrast; confirm colour processing and exposure in the trial.
Proposed component
LS-KF1628M-ML
Proposed 16 mm C-mount macro lens. The illustration uses its printed 0.1x magnification at 152 mm working distance. The proposed camera sensor gives a derived 84.456 × 70.656 mm field. Confirm field, focus and residual distortion on the actual sample; this is not calibrated measurement accuracy.
Proposed component
LS-RS7430-UV365
Current 365 nm UV ring proposed for a new trial: 74 mm OD, 40 mm opening, 20 mm high. The source names a different 74 mm-family UV ring version; its angle and aperture are not the same.
Proposed component
LS-BT-XZ-G-6-6045
600 mm column, 600 × 450 mm breadboard, XZ adjustment, glass tray and two lighting holders as listed. Proposed bench fixture; confirm loads, travel and camera/lens clamps.
Inspect the real capture
Follow the contrast to the part.
Use fluorescence contrast to inspect the bead shape, then validate the bond by the required method.
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.

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.

Lighting application-lab catalog capture
Evidence you can inspect
Visible in the images
The bead path and two internal adhesive marks appear brighter than their surroundings.
What the source reports
The source reports a 365 nm UV lighting arrangement for glass adhesive-break inspection, without bead dimensions or quantified detection results.
How to use this evidence
A single source image. It does not establish UV response for another adhesive formulation or guarantee that every visible gap is a failed bond.
What the camera saw
Cropped from the source test sheet; original test annotations are retained. Captures are not generated or enhanced. Drag the comparison slider or use the image buttons.
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.
From image contrast to a production decision
What to validate on your part
A useful sample image is the starting point. These are the checks that turn the concept into a defensible inspection.
- 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.
Explore your inspection requirementsNo limit from motion
How many pixels cover your feature?
Compare feature coverage, camera pixel requirements and exposure using your own planning inputs. These are calculated planning values, not inspection results or an accuracy specification.
Editable planning scenario. Adjust these example inputs for your application; they are separate from the source test and 3D setup. Motion allowance and target coverage are starting points to validate, not acceptance limits. Pixel count starts from the proposed camera's catalog resolution.
Enter finite numbers in every field. Field width, feature width, target coverage, exposure and allowed motion must be greater than zero; horizontal pixel count must be a positive whole number; material speed may be zero. Use values within the supported numeric range if a calculation cannot be represented.
Object sampling mm/px
Pixels across feature px
Horizontal pixels for target px
Motion during exposure px
Exposure ceiling from motion µs
Formulas and assumptions
The field, feature, speed and exposure start with neutral example values. They are not taken from the source test or the 3D illustration. Allowed motion starts at an editable 0.5-pixel example; it is not a recommended acceptance limit. Target coverage starts at an editable 5-pixel example; it is not a recommended detection or measurement threshold. The horizontal pixel count starts from the catalog Resolution row for MV-CS050-10GC. Use the effective width after cropping, binning or decimation if those modes are enabled.
- Object sampling (mm/px) = field width (mm) / horizontal pixels.
- Pixels across feature = feature width (mm) / object sampling (mm/px).
- Horizontal pixels for target = field width (mm) × target pixels across feature / feature width (mm), rounded up to a whole pixel.
- Motion (px) = speed (mm/s) × exposure (µs) / 1,000,000 / object sampling (mm/px).
- Exposure for allowed motion (µs) = allowed motion (px) × object sampling (mm/px) / speed (mm/s) × 1,000,000.
The exposure result is the maximum duration from this motion allowance alone. At zero speed, motion sets no exposure limit; the camera, lighting, saturation and other constraints still apply. A shorter exposure does not itself guarantee a reliable inspection.
Field width and feature width refer to the same object plane. The motion calculation assumes uniform linear motion parallel to the field-width direction and a single exposure. It does not model perspective, vibration, rolling-shutter distortion, diffraction, defocus or optical distortion. A strobe may change the effective exposure.
The target result is a horizontal sampling requirement, not a camera recommendation or a change to the selected camera. It uses the effective image width after cropping, binning or decimation and does not determine the vertical resolution or sensor size. Pixel coverage alone does not establish detectability or measurement accuracy. Validate contrast, lens performance, working distance, illumination, calibration, camera exposure limits and the inspection algorithm on representative parts. Changing field width does not change the 3D model or certify that the proposed lens can achieve that field.

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.
