Thus the daytime exit pupil is not a universally desirable standard.

They also have large exit pupils making centering less critical and the narrow field of view works well in those applications.

The virtual image of the aperture from inside the camera is the lens's exit pupil.

The exit pupil is the image of the aperture stop in the optics that follow it.

The exit pupil of an eyepiece was once called the Ramsden disc in his honour.

Often night glasses also have a fairly large exit pupil of 7 mm or more to let all gathered light into the user's eye.

The term exit pupil is also sometimes used to refer to the diameter of the virtual aperture.

An exit pupil at infinity makes the lens image-space telecentric.

Friends accustomed to receiving advice on all things optical are often met with confusion when they ask "What's the best exit pupil diameter?"

The corresponding image of the aperture as seen through the back of the lens system is called the exit pupil.

The location of the exit pupil thus determines the eye relief of an eyepiece.

By contrast, 8x32 binoculars, often sold with emphasis on their compactness, have an exit pupil of only 4 mm.

The larger front lenses in the 8x40 also produce wider beams of light (exit pupil) that leave the eyepieces.

In optics, the exit pupil is a virtual aperture in an optical system.

Adjustment for the interpupillary distance, is done in software, although given its large exit pupil, this should not be a severe issue with the Rift.

The terms Entrance pupil and Exit pupil are used in optics.

In that case, the exit pupil can be easily calculated as the diameter of the objective lens divided by the magnification.

This is mounted in front of the telescope eyepiece and used to evaluate the diameter of the exit pupil.

Exit pupil, the equivalent location of the pinhole in relation to the image plane in a real camera.

The concept of exit pupil is not often discussed in analog photography, but has become increasingly important in digital imaging.

The closer the exit pupil to the focal plane, the higher the angles of incidence at the extreme edges of the field.

The exit pupil can be visualized by focusing the instrument on a bright, nondescript field, and holding a white card up to the eyepiece.

An entocentric lens is a compound lens which has its entrance or exit pupil inside the lens.

It requires the middle of the aperture stop to be reproduced in the centers of the entrance and exit pupils without spherical aberration.

Devices such as stereo microscopes have small exit pupils, and adjustment for user IPD is necessary.
