Electron Microscopy Sciences EMS Gold Aperture with 200 µm hole, 3 mm O.D., 0.24 mm thick

Supplier: Electron Microscopy Sciences 44200AU

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.
