Key Takeaways Off-axis innovation: OAP mirrors eliminate central obstruction and aberration, enabling diffraction-limited focusing and ultra-smooth beam collimation. Precision fabrication: Avantier achieves λ/20 to λ/50 surface accuracy and <0.2 nm surface roughness through advanced diamond turning, magnetorheological, and ion beam polishing. Material optimization: Tailored substrates—from oxygen-free copper to silicon carbide and CFRP—ensure thermal stability and […]
