Z-stacking involves scanning at multiple focal planes along which axis?

Explanation:
Z-stacking works by capturing images at different depths through the sample, moving along the Z-axis—the depth direction along the optical axis of the microscope. Each image is taken at a slightly different focus position, so stacking them creates a composite with greater depth of field or a 3D view of the specimen. The X and Y axes move the stage sideways to image different areas, but they don’t change how deep you’re focusing. A W-axis isn’t part of this typical setup, so it’s not relevant for Z-stacking.
