Clutch-plate springs: expose the window patterns with transmitted light
The source backlit capture shows four spring-window regions within a dark circular clutch plate. Their repeated patterns provide a practical starting point for an assembly-appearance trial, without demonstrating spring force or clutch function.
Use the spring-window pattern for appearance and prove mechanical function separately.

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.

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 repeated spring pattern can vary with part orientation and fixture position.
The trial must distinguish a changed assembly from accepted differences in spring appearance and window edges.
How it was solved
The source identifies the white backlight for inspecting the springs of a clutch plate. Transmission separates the plate and spring-window patterns from the bright background.
Test known assembly states using the proposed camera and lens. The illustrated plate is a representative bench specimen; the source does not give its diameter.
Why it works
- 1
A transmitted field makes openings and interrupted light paths available for geometric pattern checks.
- 2
Visible spring appearance cannot establish preload, rate, fatigue condition or clutch performance.
Lighting application-lab catalog capture
Evidence you can inspect
Four repeated spring-window patterns, other openings and a central hole are visible in the dark plate silhouette.
The source captions inspection of the springs of a clutch plate under a white LS-HFS150100.
No required spring count, assembly decision, source dimensions, spring-force data or functional result is supplied.
From image contrast to a production decision
What to validate on your part
- 01
Label the assembly states
Use verified accepted, missing, displaced and incorrect-spring samples where applicable to the actual design.
- 02
Test placement and orientation
Cover allowed loading variation and ensure every required window remains visible.
- 03
Keep functional testing separate
Validate appearance decisions independently of spring-force or clutch-function acceptance.

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.

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.
