Application study · High-speed inspection developmentMetal positioning at a source-reported 4 µs exposure
The source pairs a bright rectangular metal target with a 4 µs exposure and a strobe coaxial light. It demonstrates useful signal at that short exposure; the source does not state that the target was moving or report a production speed.
A short exposure needs a verified light-and-trigger recipe before it becomes a motion-freezing claim.

Proposed component
MV-CS050-10GC
5 MP colour global-shutter camera; its published UltraShort 1–14 µs mode includes the source-reported 4 µs exposure. Proposed camera only: confirm exposure and strobe timing together.
Proposed component
LS-KF3528M-ML
Proposed 35 mm C-mount macro lens. The illustration uses its printed 0.25x magnification at 150 mm working distance. The proposed camera sensor gives a derived 33.7824 × 28.2624 mm field. Confirm field, focus and residual distortion on the actual sample; this is not calibrated measurement accuracy.
Tested component
LS-SCOS40
White strobe coaxial light explicitly named in the source target example; printed 70 × 47 × 46 mm housing and 38 × 39 mm emitting area. Requires its matched strobe controller.
Proposed component
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.

A short exposure needs a verified light-and-trigger recipe before it becomes a motion-freezing claim.
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 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
Use the matched LS-BPS24120C-4TD strobe controller identified in the light specification, subject to supplier confirmation of the complete light, pulse and duty-cycle recipe. Confirm triggering, cables and PC. A standard steady-output light controller is not a substitute.
Lighting application-lab catalog capture
Evidence you can inspect
Visible in the images
A bright rectangular target is visible against the darker background.
What the source reports
The source explicitly gives a 4 µs exposure for this strobe-coaxial metal-positioning capture.
How to use this evidence
The source supplies no movement speed, pulse duration, trigger jitter or positioning accuracy. It cannot establish a production inspection rate.
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.
The challenge
Short exposures reduce collected light. A sharp edge can become unusably dark before its motion blur is small enough.
Camera exposure, light pulse, trigger timing and ambient light all contribute to the final image.
How it was solved
The catalog identifies the white LS-SCOS40 and labels this metal-positioning capture with a 4 µs exposure. It gives no target speed or pulse-width measurement.
The proposed MV-CS050-10GC supports a published 1–14 µs UltraShort exposure mode. Its timing and strobe synchronization still need to be verified with the matched controller.
Why it works
- 1
A synchronized strobe can deliver useful light during a short camera exposure.
- 2
Object travel is speed multiplied by effective exposure time. A calculated travel value is an engineering scenario, not a measured blur or demonstrated throughput from this source.
From image contrast to a production decision
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
Measure the timing
Verify camera exposure, light pulse, trigger delay and jitter together.
- 02
Test actual movement
Image the real target at maximum speed and compare edge localization and blur.
- 03
Check the thermal recipe
Confirm controller compatibility, pulse current, permitted duty cycle and ambient-light rejection.
Explore your inspection requirementsNo limit from motion
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.

Pixels across feature px
Horizontal pixels for target px

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-CS050-10GC. 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.
