Aberration and its type ?
Answers
Answer:
What is Optical Aberration?
In an ideal lens, light from any given point of an object would pass through the lens and come together at a single point in the image plane. Contrary to ideal lenses, real lenses do not focus light to a single point. These deviations from the idealized lens performance are known as an aberration of the lens.
Explanation:
Types of Aberration
When the light of a single wavelength is considered, there are five monochromatic aberrations to be considered and they are:
- Spherical Aberration
- Coma
- Astigmatism
- Curvature of Field
- Distortion
ᴀɴsᴡᴇʀ:-
In optics, aberration is a property of optical systems such as lenses that causes light to be spread out over some region of space rather than focused to a point. Aberrations cause the image formed by a lens to be blurred or distorted, with the nature of the distortion depending on the type of aberration.
