Optics exit pupil
WebThe distance between the exit pupil and the last optical surface (or the geometrical end of the ocular lens) is called the eye relief; it can be inconveniently small for some ocular lenses with a short focal length. The … WebThe pupils of an optical system are images of the aperture stop; typically, machine vision lenses have embedded aperture stops, with individual lens components surrounding it on either side. The entrance pupil is the image of the aperture stop into object space, and the exit pupil is the image of the aperture stop into image space.

WebJul 17, 2006 · The exit pupil is a small circle just behind a telescope through which all emerging light rays pass. You can see it as a little disk of light floating in the air behind the eyepiece when the instrument is pointed at a bright surface, such as a wall or the daytime sky. This disk is an image of the telescope's aperture. WebThe exit pupil is the image of the aperture stop when it is imaged through the following lens elements into image space. In an optical system, the aperture stop and the pupils are used to define two very important rays.
WebDec 4, 2016 · The entrance and exit pupils--which together are known as the pupil planes--are the planes in which the images of the system's aperture stop are located. The pupil function, however, is not an image of the aperture stop of the system; it's a 2D Fourier transform of a field. WebIn general, an optical system has one effective aperture, and the entrance pupil is formed by all lenses preceding the stop, whereas the exit pupil is formed by all lenses following it. In …

In optics, the exit pupil is a virtual aperture in an optical system. Only rays which pass through this virtual aperture can exit the system. The exit pupil is the image of the aperture stop in the optics that follow it. In a telescope or compound microscope, this image is the image of the objective element(s) as produced by … See more To use an optical instrument, the entrance pupil of the viewer's eye must be aligned with and be of similar size to the instrument's exit pupil. This properly couples the optical system to the eye and avoids See more The distance of the exit pupil from the sensor plane determines the range of angles of incidence that light will make with the sensor.
