Another important aspect of binoculars is how much light you can still see well with them. Here you can choose in which light you want to use your binoculars.
The luminous intensity of binoculars is mainly determined by the size of the exit pupil. You can think of the exit pupil as a beam of light that is a certain size and falls directly through the pupil onto the optic nerve, where it provides the image. As it gets darker, the pupil opens a little more to allow more light to enter. So the larger the exit pupil, the more suitable a pair of binoculars is for low light conditions. We recommend an exit pupil of
4 millimeters for ordinary use. For hunters who prefer to be out and about at dusk, however, the exit pupil should be at least
6 millimeters in size. To help you easily get an overview of
the possible exit pupils, we have divided them into a few sections for you.
