Key Takeaways:
Optical mirrors need nanometer-scale form accuracy. Hydrostatic rotary tables provide the vibration-free, thermally stable rotation required for aspheric and parabolic mirror machining.
Form Accuracy at the Nanometer Scale
Non-spherical optical elements—aspheric lenses and parabolic mirrors—demand form accuracy in the nanometer range. Any vibration or thermal drift during diamond turning or grinding corrupts the surface. A hydrostatic rotary table floats the workpiece on a stable oil film, isolating it from spindle and floor vibration.

Stable, Repeatable Optics Production
With ±0.001 mm rotary positioning and oil-film damping, the Marusaku table supports consistent, chatter-free cutting of optical substrates. The air-curtain seal keeps the oil film clean, protecting sensitive optical work from contamination.
Why It Matters for Optics
Mirror surfaces are only as good as the motion that creates them. Hydrostatic support removes the runout, crawl, and thermal error that limit conventional tables, enabling true nanometer-class optics.
