Disc apertures, Gold

Advanced techniques of thin metal film application permits the apertures to retain a clean hole edge during prolonged beam exposure. Ultra-thin, half-micron design discourages contaminant accumulation and stabilises astigmatic conditions to provide longer life. Conventional mechanical cleaning involving costly down-time is no longer necessary. Because the foil is ultra thin, care must be taken when handling the gold foil apertures.

Gold foil aperture tolerances vary as follow:

  • Nominal hole size from 1 to 60 micron: +/-1micron
  • Nominal hole size 70 micron and up: +/-10%
