APLANAT Meaning and
Definition
-
Aplanat is a term that pertains to optics and refers to a type of lens system that is designed to eliminate or minimize certain optical aberrations, particularly spherical aberration and astigmatism. The word aplanat is derived from the Greek words "a" meaning ‘without’ and "planos" meaning ‘wandering’ or ‘distorted’.
An aplanat lens system consists of multiple lens elements or surfaces that are specifically designed to correct for these aberrations. By utilizing a combination of convex and concave lens elements made from different optical materials, an aplanat system can effectively correct for the distortions of light rays passing through the lens. This allows for a clearer and more precise image formation, resulting in improved image quality and resolution.
The main distinguishing feature of an aplanat is its ability to produce an image where the focus is independent of the position within the field of view. This means that regardless of where an object is located within the lens system's field of view, the image will be sharp and free from distortion. This characteristic makes aplanats particularly useful in photographic lenses, telescopes, microscopes, and other optical instruments where high image quality and accuracy are crucial.
In summary, an aplanat is an optical lens system that is designed to correct for spherical aberration and astigmatism, resulting in improved image quality and a consistent focus across the field of view.

Etymology of APLANAT
The word "aplanat" originated from the German term "Aplanat", which was coined by the German physicist and optician Ernst Abbe in the late 19th century. It is derived from the Greek prefix "a-" meaning "without" or "not" and the Greek root word "planos" meaning "wandering" or "roaming". "Aplanat" was used to describe a type of lens that corrected spherical aberration, hence providing a flat (non-wandering) image.
