Polishing Error Correction for Lenses and Mirrors

The scia Finish 1500 is used for surface form error correction of high-precision optical elements. The system is suitable for high volume production with 24/7 operation due to fast pumping times and high removal rates of the ion beam source.

Features & Benefits

  • Long term stable process for repeatable quality of optical components
  • Excellent precision on large areas
  • High removal rates for high throughput
  • Easy loading of large substrates due to sliding doors
  • Designed for high volume production with short pump down times

Applications

  • Final surface form error correction of lenses and mirrors
    • Telescope mirrors (Zerodur®, SiC, LTEM)
    • Conventional optics (quartz and other glasses)
    • Ion beam figuring of X-ray optics (Si)
       

Application Note

Principle

  • Focused broad ion beam scans across substrate surface in vertical setup for low contamination
  • Dwell time control to remove different amounts of material
     

Technologies

Ion Beam Figuring (IBF) is a polishing error correction by a scanning ion beam and dwell time control.
