Which outcome results when an electron beam's collimation fails in an electron microscope?

💡 Explanation

Beam collimation failure causes aberration and image distortion because increased electron trajectories deviate from the ideal focal point due to **spherical aberration**; therefore, this results in a blurred image rather than increased temperature or enhanced coherence via other optical mechanisms.
