Server chassis: check the screws on a large metal panel under a white panel light
The source colour image shows part of a metal server panel under a white panel light. Screws with toothed lock washers and smaller six-lobe screws are visible across the brushed, stained surface.
Check each expected screw position, not only the total count.

Camera and available lens CAD are published models. Lens and light envelopes use printed dimensions. The aluminium-profile gantry, its brackets and the work surface are generic illustrations, not catalog items. Light paths explain the arrangement and do not simulate optical performance. Representative part geometry is illustrative, not reconstructed inspection evidence. The specimen and lighting distance are representative, not dimensions or settings recovered from the source capture. The panel is drawn near the lens so the drawn viewing envelope passes through its 50 mm opening at the long working distance; this spacing is a proposal, not the source arrangement.
Lighting manufacturer's catalog test image
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 large chassis carries many screws of several types, and a missing or wrong screw is easy to miss by eye.
The metal panel is uneven in colour and finish, so the screws must be found against stains and scratches.
How it was solved
The source identifies the white 400 × 300 mm side-lit panel light with a 50 mm round centre opening for counting the screws on the surface of a large server.
Look through the opening with the proposed colour camera, find each screw at its expected position and flag empty or wrong positions. The published image is cropped at the left to remove stamped letters; the source does not name its camera, lens or software.
Why it works
- 1
A large panel close to the camera axis lights the flat chassis evenly, so round screw heads and washers stand out by shape.
- 2
Checking each expected position, rather than only the total, also catches a screw in the wrong hole; the source gives no detection rate.
Lighting manufacturer's catalog test image
Evidence you can inspect
Larger screws with toothed lock washers and smaller six-lobe screws are visible across the stained metal surface.
The source captions the example as counting the screws on the surface of a large server and identifies the white side-lit panel light.
One cropped source capture of part of the panel. No panel size, screw count, cycle time or detection rate is supplied.
From image contrast to a production decision
What to validate on your part
- 01
Map every position
Record the expected screw type at each hole from the assembly drawing.
- 02
Seed assembly faults
Include missing screws, wrong screw types, missing washers and loose screws.
- 03
Cover the whole panel
Confirm the full chassis is evenly lit in the field, or plan several views.

"Tested" marks the part the manufacturer used in its application test. "Our pick" is our proposed alternative or supporting part, not tested by the manufacturer in this set-up. Confirm colour, optics, controllers, power supplies, cables and mounting before ordering.
The set-up
| Tested light | LS-BKL-0803, white |
|---|---|
| Source camera / lens | Not specified in the source image caption; proposed parts below |
| Proposed lens point | 0.03x at 546 mm, printed lens pair |
| Derived proposed field | 281.52 × 235.52 mm = sensor dimensions / 0.03x; not a source test field |
| Luminous size (printed) | 400 × 300 mm |
| Panel envelope (printed) | 432 × 332 × 10.5 mm; 50 mm round centre opening |
| Source light position | Not supplied; the camera is shown looking through the centre opening |
| Mounting (proposed) | Aluminium-profile gantry built to suit, not a catalog item: two posts outside the panel and the viewing field, a camera crossbeam above and two light crossbeams beside the panel |
Mount the optics with intent
This panel light is too large for the catalog test stations' column clearance, so the 3D scene shows a generic aluminium-profile gantry instead: two posts outside the panel and the camera's field, a crossbeam the camera hangs from and two crossbeams that carry the panel. The gantry is an illustration of a frame to build or source to suit; it is not a catalog product and is not part of the quote. Profile sizes, joints, brackets and the work surface are schematic: confirm stiffness, camera and light fasteners and clearances before building.
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.

Representative part geometry is illustrative, not reconstructed inspection evidence. The specimen and lighting distance are representative, not dimensions or settings recovered from the source capture. The panel is drawn near the lens so the drawn viewing envelope passes through its 50 mm opening at the long working distance; this spacing is a proposal, not the source arrangement.
