Mirror-surface appearance: separate reflected structure from local damage
The source image shows a reflective mirror-like face with broad brightness structure. It is captioned as a surface-pit inspection example, but no isolated pit or quantified defect threshold is identified in the evidence.
Prove a local defect signal before interpreting a reflected brightness pattern.

Explore it in 3D
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 specimen and lighting angle are representative, not dimensions or settings recovered from the source capture.
Lighting application-lab catalog capture
What the camera saw
Cropped from the source test sheet; original test annotations are retained. Captures are not generated or enhanced. Drag a comparison slider, or open any image full size.
The challenge
A reflective face returns the illumination structure as well as any surface defect.
Normal curvature, coating and placement changes can produce a larger brightness change than a small local pit.
How it was solved
The source identifies the white flat coaxial light and labels the application rearview-mirror surface-pit inspection. The supplied image does not label or measure a particular pit.
Use known local defects and accepted mirrors to decide whether the reflected appearance yields a stable signal. The proposed representative 3D mirror is not a reconstruction of the source surface.
Why it works
- 1
A broad light-guide arrangement can make changes in reflected appearance available to the camera.
- 2
Brightness structure alone cannot establish local damage, surface flatness or a numerical pit size.
Lighting application-lab catalog capture
Evidence you can inspect
Broad reflected brightness structure and part boundaries are visible.
The source captions the application mirror surface-pit inspection using the white LS-CXL-0184.
No specific pit is labelled; no pit dimensions, flatness measurement, defect map or detection result is supplied.
From image contrast to a production decision
What to validate on your part
- 01
Use verified local defects
Include independently known pits and accepted coating or curvature variation.
- 02
Change the placement
Test normal tilt, part position and reflected background changes.
- 03
Define a local signal
Confirm that a defect rule separates small damage from broad illumination structure at final exposure.

|---|---|
| Source camera / lens | Not specified in the source image caption; proposed parts below |
| Proposed lens point | 0.1x at 152 mm, printed lens pair |

Mount the optics with intent
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.
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.

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.
