A crystallographic direction shared by a set of planes. Aligning a transmission electron microscopy beam along a suitable zone axis can excite multiple useful lattice reflections.
The reciprocal vector of a plane containing the real-space direction is perpendicular to that direction, giving in consistent crystallographic indexing. For a cubic zone, allowed plane indices satisfy .

The term "zone axis" is commonly used in the context of crystallography and materials science, particularly in electron microscopy and diffraction studies. It refers to a specific direction in a crystal lattice that is used to analyze the orientation and symmetry of the crystal structure. In more detail: 1. **Crystallography**: In crystal structures, the zone axis is a line that represents the intersection of a series of lattice planes.
