Ted Pella 61030 Electron Microscope Aperture 30um

The Ted Pella 61030 Electron Microscope Aperture provides precise beam control in TEM and SEM systems with a 30 µm aperture, designed to limit beam divergence and improve imaging resolution. This direct replacement aperture disc has a 3 mm outside diameter (series configuration) and a typical thickness of 0.25 mm, crafted from precision metal aperture foil for stable electron beam shaping. It is compatible with transmission and scanning electron microscopes that use 3 mm aperture holders and is commonly used in materials science, semiconductor inspection, nanotechnology, and life sciences laboratories for beam alignment, imaging optimization, and routine instrument maintenance. Manufacturer: Ted Pella, Inc.; MPN: 61030. Related replacements include 61020 (20 µm), 61040 (40 µm), and 61050 (50 µm).
