DESCRIPTION

Shadow cast carbon replicas of diffraction line gratings (spacing 462.9 nm) which are used typically for calibrating electron-optical magnifications up to the x80,000 to x100,000 range.

Rulings of 2160 lines/mm, ruled at 90° to one another, give additional accuracy to magnification checks and aid in checking distortion. These replicas should be used with care, avoiding excessive exposure at high probe/beam currents.

This standard for calibration, provides a double-check of the accuracy of magnification calibration and is particularly useful for higher magnifications. The latex sphere size is 0.261µm and the grating replica is 2160 lines/mm. Supplied on a 3.05mm grid.
