MV-CS050-10GM(NPOE)View part & specifications →Browse camera options →PCB panels: keep edge sockets and repeated outlines visible
Two real board-panel tests show the same practical issue: the edge of the field is dimmer than the centre. An arc bar keeps repeated outlines and connector positions more consistently visible.
A repeated feature needs repeatable illumination wherever it lands.

MV-CS050-10GM(NPOE)
5 MP monochrome global-shutter camera, 2448 × 2048 pixels, 3.45 µm pixels and C-mount. Proposed for a bench contrast trial; the source does not identify its camera. Requires separate camera power; this NPOE model does not support PoE.
LS-KF1628M-ML
16 mm C-mount macro lens; its printed 0.1x at 152 mm working distance gives a derived 84.46 × 70.66 mm field on the proposed camera. Confirm coverage, focus and the required smallest feature.
LS-LBR18020
Arc bar used in both clearer source captures; one proposed bar.
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.
Follow the contrast to the part.
A repeated feature needs repeatable illumination wherever it lands.
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.

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.
Configure the mounting station →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.
Evidence you can inspect
Two panel types show more consistent feature brightness in the arc-bar captures.
The source captions report improved spot coverage and uniformity; no defect recall, false-call rate or minimum feature is given.
A lighting application-lab 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 original tested system.
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.

Straight barArc barArc bar: Same application sheet with the arc bar; repeated round outlines remain clearer across the field.

Straight bar · connector panelArc bar · connector panelArc bar · connector panel: Second board type under the arc bar: the connector positions are more evenly visible.
The challenge
Panelized boards repeat the same feature at many positions. A threshold that works in the middle can fail at the edge when the illumination falls off.
How it was solved
Both source sheets compare white LS-4BR25030 with white LS-LBR18020, first on round board outlines and then on a panel with repeated connector positions.
The proposed optical kit is a stationary contrast test. It is not a complete solder-joint AOI system and does not establish electrical continuity.
Why it works
- 1
A more even light distribution reduces position-dependent brightness differences.
- 2
The two board types provide related trials of coverage, not two independent production success stories.
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
Inspect every position
Place identical reference regions at the centre, sides and corners of the intended field.
- 02
Challenge the classifier
Include acceptable solder-mask colours, silkscreen and connector metal finishes.
- 03
Verify the actual field
Choose magnification for the real panel size and confirm that all required features fit at the chosen resolution.
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.
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-CS050-10GM(NPOE). 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.
