Single Hole Disc Apertures

  Single Hole Disc Apertures

One of the most important factors in obtaining high resolution in both transmission and scanning electron microscopy  is the quality of apertures used in the system. We offer a wide selection of these highest quality, high precision apertures. The utmost care and European craftsmanship combine with the most advanced technology to produce these extremely high quality apertures.
