  • 0.1 mm – 50 mm (depending on size)

Tolerances

  • Planarity: up to λ/10 (select ≤ 6 for diameter-to-thickness or diameter-to-greatest-edge length ratio depending on size), diameter or edge length can be measured up to 250 mm diameter. Documented proof available for up to 150 mm on request
  • Parallelism: up to 1″ depending on dimensional details or
