WebApr 17, 2014 · PUPIL • Formally, a pupil is an image of the aperture stop. • There are 2 types of pupils – 1.Entrance pupil – 2.Exit pupil. 6. ENTRANCE PUPIL • The entrance pupil of a system is the image of the aperture stop as seen from a point on the optic axis in the object plane. • The entrance pupil takes over the role of the lens rim in the ... WebEntrance and Exit Pupils. Figure 1.7 Simple lens system and aperture stop. In the case of a lens with an internal aperture stop, as in Fig. 1.7, the concepts of entrance pupil and exit pupil are particularly important. If we view the lens in Fig. 1.7 from the object space, we see an image of the aperture stop, known as the entrance pupil.

If the relay lens diameter is larger than this image, all of the light from an object point collected by the objective will be transferred to the second image. For an optical system used with the eye, the final field lens will not image the relay lens aperture into the eye lens, but rather to the exit pupil ...
WebApr 12, 2024 · The biological pupil of the eye is its aperture in optics nomenclature; the iris is the diaphragm that serves as the aperture stop. Refraction in the cornea causes the effective aperture (the entrance pupil in optics parlance) to differ slightly from the physical pupil diameter. 1. 1. 1. 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.
