Manufacturing evidence layer

Verification evidence that can move a milestone.

Fairbuild is not selling metrology hardware as a separate catalog. It uses MTF, SFR, ToF, and eye-tracking radiometry artifacts as the proof layer for quality gates, review windows, and settlement instructions.

From station to settlement

Hardware evidence becomes a payable milestone.

The product line is designed around one operational fact: a unit has not earned settlement until the measured evidence clears the agreed quality gates.

Wafer Level Optics

Production-ready WLO and compact camera module stations.

One architecture for MTF, flat-field, optical distortion, and multi-camera calibration, packaged for factory-floor repeatability.

Alignment station

Automated precision self-alignment.

Twin independent cameras track alignment between the test chart and camera module, holding sub-10-µm positioning and recalibrating on a production schedule.

  • Closed-loop chart and DUT alignment
  • Scheduled self-calibration every 4 hours
  • Per-unit alignment evidence attached to QA records

Auto-socketing

Quad sockets built for throughput.

Custom-machined sockets and self-alignment mechanics keep camera modules seated repeatably across high-volume line operation.

The line software exposes the operating details buyers care about: recipes, fixture state, containerized deployment, and export-ready evidence.

Specialized suites

Radiometry, SFR, and ToF programs covered by measured gates.

Each suite maps the physical test to a clear QA record: measured output, acceptance threshold, trace, and manufacturing handoff.

Eye tracking radiometry

NIR source verification for eye-tracking assemblies.

Verifies VCSEL and LED output against eye-safety and uniformity gates across manufacturing stages, with encrypted production logs attached.

Uniformity97.4%
Eye-safety gatelocked
Circle SFR

Sagittal and tangential response checks.

Compares measured SFR against optical-simulation results to catch lens and sensor misalignment before the issue reaches final assembly.

ToF calibration

Direct and indirect Time-of-Flight coverage.

Evaluates VCSEL drivers, range response, and calibration stability across working distances up to 15 meters.

Turn factory evidence into payable milestones.

Bring the QA artifacts your factory already creates. Fairbuild will map them to gates, review protocol, and settlement instructions.
