/ Polygon Mirrors

Materials:
  • Oxygen Free Copper (OFHC - Cu)
  • Aluminum (6061 & 6082 Preferred Grade)
  • Brass
  • Plastics (PMMA)
  • Crystalline Materials
  • Non-Ferrous Metals
Flat Dimensions:
  • 10mm to 500mm (Approximate)
Planarity:
  • Lambda/10 Visible Spectral Range (Approximate)
  • Ruling Errors: 1 arcsec
  • Pyramidal Errors: 1 arcsec
Surface Roughness:
  • Ra 1-5 nm (Dependent on Material used)

Faceted or polygonal mirrors are found in a variety of counting, scanning, measuring and machining applications.

All mirrors are precisely manufactured on LT ULTRA precision fly-cutters, which can produce angle tolerances in the order of ± 1 arc second and surface finishes between 1nm and 5nm (Ra).
