ArCarb-HPSHigh Precision Structures
ArCarb-HPS is specifically tailored for high precision systems where co-efficient of thermal expansion of a component can highly influence the output of a system. ArCarb-HPS combines fiber architecture and design expertise to obtain near zero co-efficient of thermal expansion along with significant weight reduction.

Advantages
- Near zero coefficient of thermal expansion for highly accurate mechanism
- Lightweight structures due to low material density (1.9 g/cm3 ) and thin walled geometries (t ≥ 0.15mm) for fast moving components
- Environmentally stable. No swelling or detectable outgassing in vacuum allows the use of our composite near optics
