Application study · Glass containers and liquid productsVials: collect side-view contrast from end illumination
The real source result shows small bright features in a vial against a dark field. Light enters from an end while the camera views the side, an arrangement worth testing when direct background light masks the feature of interest.
Separate a bright-feature image from a verified particle decision.

Proposed component
LS-2SL083
Proposed white second-generation spot light:24 mm body diameter,62 mm length,6 mm emitting port and3 W. Requires a compatible constant-current driver; its exact drive current is not printed in this catalog record.
Proposed component
LS-BT-XZ-G-6-6045
600 mm column, 600 × 450 mm breadboard, glass tray and two lighting holders. Proposed bench fixture; actual load, travel, clamps, mounting fasteners and light clearance must be confirmed.

Camera and available lens CAD are published models. Light envelopes and the station base/height use printed dimensions. Part shapes, brackets, holders, shielding and spacing are illustrative; they are not reconstructions of a source part or a complete mechanically validated assembly. Light paths explain the proposed arrangement and do not simulate optical performance. The proposed field is derived from the printed camera pixel dimensions and the stated lens magnification/working-distance pair, not measured from the source capture.

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.

Lighting application-lab image sheet
Evidence you can inspect
Visible in the images
The supplied side-view capture contains small bright features against a dark vial field.
What the source reports
The source gives a spot-light arrangement and annotated result but no exact source model, colour, camera, liquid, particle identity or size limit.
How to use this evidence
An application-lab lighting demonstration, not a customer deployment or a qualified production inspection. Proposed camera, lens, fixture and scene spacing require a fresh trial. Source observations do not establish a defect-size limit, accuracy guarantee or production false-call 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
A transparent container, liquid and glass interfaces can all scatter or reflect light. Bright features may come from particles, bubbles, glass marks or reflections, so their identity needs independent confirmation.
How it was solved
The image appears on the second-generation spot-light product page, but the exact source light model, colour and camera are not stated. The proposed white LS-2SL083 is a catalog choice, not a tested source SKU.
The source illustration stands the vial upright with a side-view camera. The proposed bench rotates that optical relationship: the vial lies horizontally in an illustrative cradle, the camera views its side from above and the spot enters through an end.
Why it works
- 1
Observing away from the direct illumination axis can separate scattered light from the main transmitted beam.
- 2
The source annotations highlight bright features but do not identify their physical cause or report a validated particle size. The image is not a sterility, pharmaceutical release or contamination certification.
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
Identify the feature
Use independently characterized particles, bubbles, clean glass and acceptable reflections.
- 02
Check the rotated fixture
Verify end coupling, support reflections, shielding and repeatable vial pose in the proposed horizontal arrangement.
- 03
Validate the real product
Measure feature visibility and false calls across the actual vial, contents and process variation; retain any required independent product-release tests.
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.
Object sampling mm/px
Pixels across feature px
Horizontal pixels for target px
Motion during exposure px
Exposure ceiling from motion µs
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.
