Mobile glass edges: use a bright field to separate the contour
The manufacturer's test image shows the corner of a mobile-device cover with a clear outer contour. It demonstrates edge visibility under right-angle coaxial lighting; a proposed straight-view coaxial kit offers a separate bench starting point.
Choose the viewing geometry around a clearly defined edge datum.

Explore it in 3D
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 part geometry is illustrative and is not reconstructed from the camera image. The proposed field is derived from the printed lens magnification and camera pixel dimensions; actual coverage and focus need a bench check. Representative part geometry is illustrative, not reconstructed inspection evidence.
Lighting manufacturer's test sheet
What the camera saw
Images from the manufacturer's application test, cropped; the original annotations are kept and nothing is generated or enhanced. Drag a comparison slider, or open any image full size.
The challenge
A thin transparent cover and its black border can reveal several overlapping edges. Reflections and the support beneath the glass compete with the contour of interest.
How it was solved
The source uses white LS-CXL-0044, a right-angle coaxial light with its camera looking from the side. The proposed LS-CXL-0025 is a straight-view alternative; its arrangement has not been tested in the source.
The 3D scene shows only the proposed straight-view geometry. Confirm clearance and edge contrast on the real cover before choosing between the arrangements.
Why it works
- 1
A controlled coaxial field can separate the border and outer edge from the surrounding region.
- 2
A clear corner image is not a full-cover measurement or a chipped-edge detection benchmark. The exact datum and acceptance rule still need validation.
Lighting manufacturer's test sheet
Evidence you can inspect
The cropped source capture retains a clearly visible curved cover edge.
The sheet reports contour visibility under right-angle coaxial illumination; no full-part tolerance or chipped-edge detection limit is given.
A lighting manufacturer's application demonstration. The source supplies no customer deployment, defect-size limit, repeatability study or production false-call data. Proposed camera, lens, field, mounting and spacing are not the system the manufacturer tested.
From image contrast to a production decision
What to validate on your part
- 01
Identify each boundary
Document whether the outside glass edge, coating border or fixture edge is the target datum.
- 02
Compare the proposed geometry
Trial straight-view and right-angle arrangements with the same representative covers and fixed exposure.
- 03
Challenge edge variation
Include known chips, acceptable bevels, border-print variation and repeated fixture loading.

The set-up
| Lighting evidence | Manufacturer test images |
|---|---|
| Camera and lens | Proposed catalog components; source camera unspecified |
| Proposed field (derived) | 33.78 × 28.26 mm at 0.25x |
| Lens working distance (spec) | 150 mm at the listed magnification |
| Mounting (proposed) | LS-MNT-0097 · 600 mm station, glass tray and two lighting 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.

About this case study: the photos and camera images are the manufacturer's application test images, supplied by the maker of the tested part and taken on the parts shown; LumaSpec did not run this test. Your results depend on your part, camera and set-up. This is a manufacturer's application study, not a LumaSpec customer deployment. Reported figures are the manufacturer's; proposed components require a fresh trial. The 3D scene illustrates the arrangement and does not simulate imaging performance.
