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.

Description

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%
