Flex-circuit positioning: retain the corner, outline and trace detail
The supplied blue-light image shows an L-shaped flexible-circuit region with visible outline and trace detail. The imaging lesson is to preserve stable geometry while accounting for the way a flexible part changes shape in its fixture.
Fixture the flex before trusting its projected position.

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
A flexible circuit can bend or curl, changing both its projected outline and its reflections.
A rule based on one trace or hole must remain stable across the accepted part and fixture variation.
How it was solved
The source identifies the blue 200 mm flat coaxial light for flexible-circuit positioning. The supplied image shows only the captured region, not a documented whole-part field.
Choose reference geometry from the actual circuit drawing and support the part consistently. Test the proposed camera and macro lens on that fixture rather than transferring a position result from the source image.
Why it works
- 1
The illumination records bright substrate regions, dark openings and fine traces as complementary visible features.
- 2
Those features can be tested for localization, but they do not establish electrical continuity or a calibrated assembly offset.
Lighting application-lab catalog capture
Evidence you can inspect
An L-shaped bright region, edge features and trace paths are visible.
The catalog labels this flexible-circuit positioning under a blue flat coaxial light.
No source circuit dimensions, fixture, position error, camera field or electrical result is provided.
From image contrast to a production decision
What to validate on your part
- 01
Control the flexible part
Specify support and flattening without stretching or damaging the circuit.
- 02
Choose robust reference features
Test features that remain stable across accepted trace, hole and outline tolerances.
- 03
Validate position and function separately
Measure localization errors independently and retain any required electrical acceptance test.

The set-up
| Tested light | LS-FCS200, blue |
|---|---|
| Source camera / lens | Not specified in the source image caption; proposed parts below |
| Proposed lens point | 0.1x at 152 mm, printed lens pair |
| Derived proposed field | 84.456 × 70.656 mm = sensor dimensions / 0.1x; not a source test field |
| Light-guide area (printed) | 200 × 200 mm |
| Housing (printed) | 240 × 240 × 10 mm |
| Mounting (proposed) | LS-BT-XZ-G-6-6045; 600 mm column, 600 × 450 mm base, glass tray and two included 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.
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. Representative part geometry is illustrative, not reconstructed inspection evidence. The specimen and lighting angle are representative, not dimensions or settings recovered from the source capture.

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.
