The space of objects ( German Objektraum , English Object space , French Espace objet ) is a set of possible positions of the points of objects - the vertices of light beams included in the optical system [1] . The term is defined in accordance with GOST as a “set of points in space”.
The space of objects is a collection of points, the image of which can be obtained using the optical system. In real systems, it is limited due to design features, that is, not all points of real space can be displayed at the same time. In the theory of optical systems, usually not all the space of objects is considered, but only its individual planes perpendicular to the optical axis [2] .
In the space of objects of any optical system are located: the front main plane, the front focus , the front focal plane , as well as the front surface of the first lens and the entrance pupil [2] .
