Midas Fiber Metalization

MIDAS Fiber Metalization system

The MIDASTM Metalization System is designed to produce a single or multi-layer symmetrical metal coating on ends, mid spans, or windows of optical fibers for use in a hermetically sealed opto-electric package. It can also create radially symmetrical material stacks on cylindrical rod or tube components.

Designed for a small clean room footprint, this load-lock system uses a low energy plasma pre-clean to ensure adhesion by removing residual hydrocarbon and water vapor contamination.

The coating chamber contains an array of sputter cathodes allowing for the uniform distribution of different metal and multi-layer coatings.

Midas System Advantages

  • Ultra-low porosity metal or dielectric coatings
  • Uses 99.99% pure metals. No phosphorus or sulfur electroplating
  • Low temperature operation allows all types of fiber jackets: acrylate, silicone, polyimide, carbon and sensitive components
  • Fully automated process control for one button operation after load-lock
  • Load-lock design streams outgas vapors away from cores during processing
  • Minimal precious metal consumption (micrograms) per component (after reclaim) for low cost per component
