  "term": "Aplanatism",
  "field": "Industrial and trades",
  "definition": "The optical property of a lens or system that is free from both spherical aberration and coma for a given pair of conjugate points. An optical system exhibiting aplanatism produces a sharp, undistorted image of a small area both on and off the optical axis. To achieve this condition, the system must satisfy the Abbe sine condition, a mathematical requirement relating ray angles to magnification.",
