arrow13Apertures and Aperture Cleaning

arrow13Self Cleaning Gold Foil Disc Apertures

Self Cleaning Gold Foil Disc Apertures 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 stabilizes 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%

arrow13Platinum Disc, Drilled Apertures

Platinum apertures are easily cleaned by either an aperture flamer or over a bunsen burner in the open air. We maintain a wide variety of Platinum Drilled Apertures in stock with different configurations suiting all of your needs.

Platinum Apertures size tolerances vary as follow:

  • Nominal hole diameter: +/- 1 micron
  • Disc diameter: +/- 10 microns
  • Disc thickness: +/- 10 microns

Ordering information: Gold (Au); Platinum (Pt); Molydenum Mo

Hole Sizes not listed are available upon special request.
