Abstract:

This paper presents and discusses the optical layouts of eyepieces for telescopic systems with variable magnification. It is shown that using optical layouts of eyepieces with a virtual front focus and eyepieces with a telecentric path of the principal rays in object space increases the region of the solutions. Relationships between the parameters of the optical layout of the eyepiece are found that ensure that the position of the exit pupil of the system varies no more than ±5 mm when the nominal relief is 95 mm. Results are presented of the development of the optical systems of zoom sights with a stable position of the exit pupil as the magnification changes.
