  • Diameters to 650mm (750mm for single-sided polishing)
  • Thicknesses to 0.25mm, size dependent
  • Transmitted Wavefront < 1 wave over the clear aperture, size dependent
  • Surface Flatness < ½ wave per inch
  • Parallelism < 10 arc seconds
  • Surface Quality 80-50 to 10-5
  • Clear Aperture 85% central
  • Bevels: 0.3mm face width @ 45°, all edges
