Sample Testing and Machine Vision Lighting Selection

Ensure optical feasibility before purchasing. Send your target inspection parts or defect images to LuxMV optical lab, or request candidate lighting units for evaluation trial. We evaluate surface reflection, contrast ratio, wavelength response, and mounting space to recommend verified lighting configurations.

Visible evidence before selection

Use product, process, facility, and inspection images to check whether the page claim is tied to a visible engineering condition.

Selection considerations

Selection follows the observable condition, the optical setup, and the production constraint.

Define the Inspection Target

Record material, surface finish, defect type, pass/fail examples, minimum visible feature, FOV, working distance, and available mounting space.

Technical considerations
  • Good and bad samples, or clear images showing the defect, feature, or measurement target.

Build a Candidate Set

Compare ring, bar, coaxial, dome, backlight, line-scan, low-angle, UV, IR, SWIR, fiber, or custom structures according to the defect mechanism.

Technical considerations
  • Test point light with coaxial or telecentric-style illumination for hidden circuits or flat reflective marks.

Test Optical Variables

Change angle, distance, wavelength, diffuser, filter, polarizer, aperture, exposure, gain, and camera position one variable at a time where practical.

Technical considerations
  • Choose continuous, analog, digital, strobe, overdrive, time-sharing strobe, or constant-current control based on exposure and heat limits.

Document Decision & RFQ Notes

Recommended light family, candidate model path, or custom-light direction.

Technical considerations
  • Geometry, wavelength, filter, diffuser, polarizer, controller mode, and camera/lens notes that produced useful contrast.
  • RFQ-ready integration notes for housing, cable, trigger, controller channel count, and mounting requirements.

Questions for the engineering discussion.

What information helps with a machine vision lighting sample test?

Send representative good and bad samples or images, part material and finish, target feature, camera and lens details, field of view, working distance, exposure, speed, trigger mode, and mounting constraints when known.

What can sample testing help compare?

Sample testing can compare lighting geometry, wavelength, filters, controller mode, and imaging settings with the supplied condition. Final suitability still depends on the real production variation and integration constraints.

What can remain open after sample testing?

Sample testing does not certify a product, predict production yield, confirm a future delivery date, or prove performance after parts, cameras, mechanics, process variation, or operating conditions change. Those points can be clarified through project-specific information and follow-up discussion.

Sample testing inputs for AI-assisted RFQ preparation

Use the same structured inputs for internal engineering review, AI-assisted sourcing, and LuxMV quotation discussion. The sample result is evidence for the supplied condition, not a blanket production approval.

Input groupWhat to provideSelection value
Samples or imagesGood and bad parts, defect photos, drawings, or short production videosShows whether a lighting setup separates the target condition from acceptable variation.
Inspection geometryField of view, working distance, camera, lens, exposure, and available spaceControls light size, angle, intensity, focus, and fixture clearance.
Surface behaviorReflective, matte, transparent, curved, coated, oily, textured, or moving materialDetermines whether to compare dark-field, coaxial, dome, backlight, polarization, or wavelength response.
Motion and controlLine speed, frame rate, trigger timing, strobe mode, controller channel count, and thermal limitsDetermines whether continuous, strobe, overdrive, or synchronized lighting is practical.
Decision boundaryWhat must be detected, measured, rejected, or escalated for engineering reviewPrevents sample testing from being treated as a universal production approval.

Application examples worth testing

Coaxial or low-angle darkfield illumination isolates directional scratch reflections while suppressing specular reflection from the polished base metal.
