Freeform Mirrors

Freeform mirrors are optics that have a non-symmetric optical surface and offer many advantages over conventional optics:

  • Improved performance
  • Redistribution of tolerances in the system design
  • Reduction of the number of optics
  • Fewer optics to align
  • Reduction of the optical system volume
  • Additional aberration correction

Using state of the art replication processes, Spectrum Scientific offers a cost effective method for the volume manufacture of freeform mirrors:

  • Aluminum or glass substrates
  • Ellipse and Paraboloid profiles
  • Size from 0.5 inch diameter
  • Typical surface figure down to λ/8 (λ/14 possible)
  • Surface roughness down to 3.5Å
  • Gold or Aluminum coating

Spectrum Scientific has considerable experience with volume manufacturing of freeform mirrors with over 10,000 mirrors shipped in 2019.
