eyepiece
[หaษชหpiหs ]
Definition
optics device
An eyepiece is a lens or a combination of lenses that is placed at the end of an optical instrument, such as a telescope or microscope, through which the user looks to view the object being examined. It magnifies the image produced by the objective lens of the instrument, allowing for a clearer and larger view of the subject. The design and quality of an eyepiece can significantly affect the performance of the optical device, influencing factors like magnification, field of view, and image clarity. Different types of eyepieces are available for various applications, including those specifically designed for astronomy and laboratory use.
Synonyms
lens, ocular, viewfinder.
Examples of usage
- The astronomer adjusted the eyepiece of the telescope.
- Make sure to clean the eyepiece before using the microscope.
- He replaced the eyepiece to get a better magnification.
- Different eyepieces offer various fields of view.

Origin of 'eyepiece'
Main points about word origin
- The word comes from a combination of 'eye' and 'piece', indicating itโs a piece designed for your eye.
- In older texts, it was sometimes referred to as an 'ocular', related to the Latin 'oculus', meaning eye.
The term 'eyepiece' originates from the combination of 'eye' and 'piece', referring to the part of an optical instrument that one looks through. The word 'eye' comes from Old English 'ฤage,' which has Germanic roots, signifying vision and sight. The term 'piece' in this context refers to a component or part of a whole instrument. The use of the eyepiece dates back to the early development of optical devices in the 16th century, coinciding with advancements in lens-making techniques. Over the centuries, eyepieces have evolved, leading to the creation of specialized designs for different fields, including astronomy, microscopy, and photography. Today, eyepieces are an essential element in various optical instruments, enabling precise examination and observation.
