Resolution

Definition

Resolution refers to the smallest distinguishable detail in an imaging system, crucial for determining the quality and clarity of the images produced. It is a key factor in various analytical techniques, as higher resolution allows for more precise measurements and better visualization of structures at the molecular level, enabling insights into protein conformations, mass-to-charge ratios of biomolecules, and interactions at a nanoscale.
