Project Details
Client: Aerospace & Satellite Company
Industry: Aerospace
Application: Space Optics
Products Used: Custom ZnSe Windows, ZnSe Prisms, Radiation-Resistant Coatings
Challenge
Extreme requirements for satellite-based infrared sensing:
- Radiation resistance to withstand space radiation environments
- Thermal cycling durability through extreme temperature swings
- Zero-defect quality with no possibility of in-orbit replacement
- Vacuum compatibility with zero outgassing
- Long-term stability over 10+ year mission lifetime
Solution
Our aerospace-grade solution with full space qualification:
- Custom ZnSe with enhanced purity and minimal internal defects
- Radiation-resistant coatings tested to 100 krad(Si)
- Comprehensive space qualification testing per ECSS standards
- Low-outgassing materials meeting ASTM E595 requirements
- Thermo-mechanical design optimization for launch and on-orbit conditions
Results
Mission success and on-orbit performance:
- Successfully deployed in orbit with nominal operation
- Exceeds expected operational lifetime with 15-year design life
- No performance degradation observed after 3 years on orbit
- Stable optical performance through thermal cycles
- Radiation tolerance confirmed through in-orbit monitoring
