Chip circuits: compare1050 and1300 nm to expose useful internal detail
The source1300 nm fibre-light capture reveals a structured circuit pattern that is far less visible in its1050 nm comparison. The result illustrates spectral visibility, not a qualified test of hidden electrical defects.
Revealing structure is a prerequisite, not a hidden-defect result.

Explore it in 3D
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 SWIR scene field is illustrative; no measured field or printed magnification/working-distance relationship is asserted. Purple is a display convention for invisible illumination.

SWIR1300 nm fibre light: Source1300 nm fibre-light capture: circuit structure is more visible.
The challenge
A dark-looking chip surface can conceal useful underlying structure. Its visible appearance is not enough to choose a near-infrared inspection band.
How it was solved
The source explicitly calls the1300 nm illumination fibre-optic but does not name its exact engine, fibre head, camera or lens. The proposed1300 nm panel is a separate transmission-trial arrangement, not the original fibre system.
An optional1300 nm fibre-light engine is also shown as a proposed alternative. Its required fibre and output head must be specified before calling that alternative a complete optical system.
Why it works
- 1
The relative transmission and reflection of the chip stack change with wavelength. A band that reveals structure can improve a later localization or comparison task.
- 2
A visible circuit pattern does not prove continuity, identify a failure mechanism or guarantee access through every package material.
Lighting application-lab image sheet
Evidence you can inspect
An underlying structured pattern is more visible in the source1300 nm capture than in its1050 nm capture.
The source names1050/1300 nm and fibre-optic1300 nm illumination; the complete source system and a defect-classification result are not given.
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.
From image contrast to a production decision
What to validate on your part
- 01
Identify the stack
Confirm the actual die/package material and the layer the inspection must reveal.
- 02
Compare light delivery
Test the proposed panel and, if needed, a specified fibre head on the same representative samples.
- 03
Use confirmed defects
Separate a visibility demonstration from defect detection by validating known good and independently confirmed defective parts.

The set-up
| Source camera | Not identified in the source sheet |
|---|---|

| Lens-to-part in proposed scene | 400 mm; illustrative spacing above printed minimum object distance |
| Mounting (proposed) | LS-MNT-0101 · catalog test station with two lighting holders |
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.
