Gold, disc, self cleaning foil disc apertures 2 mm O.D., Thickness 0.53 mm
Gold
Advanced techniques of thin metal film application permits the apertures to retain a clean hole edge during prolonged beam exposure
Gold foil aperture tolerances vary as follow:
• Nominal hole size from 1 to 60 micron: +/-1micron
• Nominal hole size 70 micron and up: +/-10%
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.
