Sub-nm Freeform mirrors manufacturing

In 30 seconds

This comprehensive manufacturing process achieves sub-nanometer RMS surface accuracy and roughness for compact freeform optical surfaces. By integrating specialized grinding, polishing, and metrology for non-spherical geometries, the technique enables high-performance optical designs with reduced system volume. This advancement facilitates the realization of compact, highly-corrected telescopes for space applications that were previously limited by traditional manufacturing tolerances.
