Design takeaway

When designing for space or vacuum, rigorously vet all materials for outgassing potential and implement strict manufacturing controls to maintain instrument cleanliness and performance.

How to apply

When selecting materials for optical systems, vacuum chambers, or sensitive electronic enclosures, consult material datasheets for outgassing data (e.g., Total Mass Loss and Collected Volatile Condensable Materials) and consider vacuum-compatible alternatives.

Project actions

  • 01When choosing materials for your design, research their properties beyond just strength or appearance, especially if your product will be used in a sealed or extreme environment.
  • 02Consider how your manufacturing process might affect the materials you use and whether it could introduce unwanted substances.

Design Principles

"Minimize volatile material emissions in vacuum-sensitive applications through material selection and controlled production."

In space environments, volatile organic compounds released from materials can condense on optical surfaces, degrading performance and compromising data accuracy. This research highlights the importance of material science and rigorous testing in the production of high-reliability components for extreme conditions.

What This Means for Your Design

For instruments going into space, it's super important to pick materials that don't release gases, because those gases can stick to important parts and mess them up.
