FIELD LENS Meaning and
Definition
-
A field lens, also known as a field flattener or a focal plane compensator, is a specialized lens that is used in optical systems to correct for aberrations and distortions that occur when light passes through a curved lens or a curved image plane. It is typically placed in the optical path near the focal plane of the system.
The primary function of a field lens is to redistribute the light rays in such a way that they have a more uniform distribution across the image plane. By compensating for optical aberrations, a field lens allows for sharper and more accurate imaging, minimizing image distortion and blurring towards the edges of the field of view.
Field lenses are commonly used in optical devices such as cameras, telescopes, microscopes, and other imaging systems. They are particularly useful in wide-field imaging applications where a large field of view is desired with high image quality.
The design and characteristics of field lenses may vary depending on the specific optical system and its intended use. They can be made from various materials such as glass or plastic and can have different shapes, sizes, and curvature profiles.
In summary, a field lens is an optical component that corrects aberrations and ensures a more uniform and accurate distribution of light across the image plane, resulting in improved image quality.

Etymology of FIELD LENS
The word "field lens" is a compound term derived from the combination of the words "field" and "lens", each with its own etymology.
1. Field:
The term "field" originated from the Old English word "feld", which meant "open land" or "plain". It can be traced back to the Proto-Germanic word "*felthuz" and the Proto-Indo-European root "*pelh₂-", which meant "flat" or "spread out".
2. Lens:
The term "lens" originated from the Latin word "lentilis", which means "lentil". It refers to the shape of a double-convex lens, which resembles the shape of a lentil seed. This Latin word was adopted into Late Latin as "lens", and then further into Middle English as "lense".
