Optical Floating Zone Furnace Ampule Growth Fixture

Overview

Built a reusable fixture architecture for optical floating zone ampule growth that minimized manual alignment and improved cycle-to-cycle consistency.

Problem / Constraints

  • Tight thermal envelope and small handling clearances
  • Frequent part swaps between experiments
  • Existing fixture introduced misalignment drift

Approach

Used datum-driven interfaces, indexed clamping features, and modular subcomponents to speed replacement while preserving repeatability.
