the visible area through the eyepiece when the microscope is in focus.
The solid angle through which an instrument is sensitive to radiation. See effective resolution element, instantaneous field of view, resolution.
(ft) Field-of-view refers to the size of the area that can be viewed through the binoculars. It can be expressed in either degrees of viewing or in the width in feet of the area visible at 1000 yards. A larger field-of-view is especially useful for following action.
In astronomy, the angular area that a telescope can 'see'.
Field-of-view is the side-to-side measurement of the circular viewing field or subject area. It is defined by the width in feet or meters of the area visible at 1000 yards or meters. A wide field-of-view is better for following fast-moving action or scanning for wildlife. Generally, the higher the magnification, the narrower the field-of-view.
The diameter of the imaged area when viewed through an optic.
The area of object space imaged at the focal plane of a camera.
