What is the primary characteristic of Plan Achromat lenses that distinguishes them from standard Achromat lenses?
Understand the Problem
The question asks about the key difference between Plan Achromat and standard Achromat lenses. It requires identifying which characteristic is unique to Plan Achromats compared to regular Achromats.
Answer
Plan Achromat lenses provide flat-field corrections and better correction for spherical aberration compared to standard Achromat lenses.
Plan Achromat lenses are distinguished from standard Achromat lenses by providing flat-field corrections, resulting in a flat image across the field of view. They also correct better for color and spherical aberration.
Answer for screen readers
Plan Achromat lenses are distinguished from standard Achromat lenses by providing flat-field corrections, resulting in a flat image across the field of view. They also correct better for color and spherical aberration.
More Information
Achromatic lenses are corrected to bring two wavelengths into focus in the same plane, while plan achromats also correct for field curvature.
Tips
A common mistake is thinking that Achromat lenses do not correct for chromatic aberration at all; they do, but Plan Achromats do it better and also correct for field curvature.
