Foceon / Platform / Optics Digital Twin

Simulate before you cut glass

The optics digital twin carries the optical prescription, the material, the tool, and the process physics for each optic. Foceon runs the next move in the twin first, so machines only make moves the simulation already trusts.

What it is

A physics-grade model of each optic and its process

The twin is not a dashboard mock-up. It is a calibrated model that predicts how a specific optic responds to a specific process on a specific tool, from removal to reflectance to wedge.

Every measurement updates the twin, and every planned move is validated against it, so the fab reasons about the future of each surface instead of reacting to its past.

Why a twin

What simulation buys a fab

Risk

Fewer scrapped blanks

A move that would ruin a high-value optic is caught in simulation, not on the machine.

Speed

Fewer iterations

Planning against a predicted surface converges faster than trial and error.

Transfer

Portable recipes

Physics-based recipes move between tools because the twin generalizes.

Insight

Explainable moves

Every action is traceable to a twin prediction, not a black box.

One twin, every physical outcome

The twin models the outcomes the fab actually sells: figure, spectrum, and alignment.

Predicted removal for a polishing pass

Predicts material removal

For grinding and polishing, the twin predicts removal per pass so dwell can be planned to close figure error.

  • Removal per tool and slurry
  • Dwell planning
  • Figure convergence
Predicted reflectance for a coating stack

Predicts spectrum and wedge

For coating and assembly, the twin predicts reflectance and cumulative wedge, so the endpoint and alignment are planned, not inspected.

  • Stack reflectance
  • Cumulative wedge
  • Endpoint and alignment
How it calibrates

From generic model to your fab

  1. Seed with physics

    The twin starts from first-principles process models.

  2. Fit to your metrology

    Predictions are tuned until they match your interferograms and profilometry.

  3. Validate on moves

    The twin's predictions are checked against real passes.

  4. Improve continuously

    Every measurement narrows the gap between twin and reality.

Inside the loop

Fast enough to sit in the control loop

Accelerated simulation makes the twin quick enough to validate the next move in real time, so it advises action rather than explaining it afterward.

Questions

How the twin works in practice

How long to calibrate?

Initial calibration runs during the pilot and sharpens continuously after.

Does it need our recipes?

It learns from your process on-prem; nothing is exported.

Which physics does it cover?

Removal, coating growth, and assembly tolerance chains today, expanding over time.
