3.0 mm diameter. Correction of astigmatism in the electron microscope can best be done using a planar specimen such as a "holey" film which is carbon coated to give good contrast for easy observation of the Fresnel fringes around the edge of the hole. A range of hole sizes is provided. From these select the optimum size round hole for your magnification requirements. When you achieve symmetry of the Fresnel fringes, astigmatism has been eliminated.

This perforated film is typically not used as a substrate. For a perforated film that is used as a substrate please see our Lacy Film.
