Osmium Aperture Plates


Osmium aperature plates boasting extreme high performance

  • The aperture plate is considered to be the heart of the electron microscope.
  • You can experience the world of high resolution simply by applying an osmium coating to your existing aperture plate.
  • Os Aperture plates are essential for high-performance functionality in FE electron microscopes and other devices including length measurement SEM, plotters, and photolithography machines.
  • We have developed our Os aperture plates to a level of performance that will fulfill your needs for high resolution.
    1. Secondary electron discharge volume has been increased.
    2. High heat resistances means a longer life span.
    3. Furthermore, we have achieved the complete prevention of electrostatic discharge.
  • These features help resolve problems related to parts replacement maintenance and thus results in lower running costs.
  • Feel free to consult us about coating for other components!
    Coating is possible for insulated materials (ceramics, resins) as well!
