In this paper the basic principles of the optical system construction for forming a cylindrical light tube of assigned diameter are formulated. It is based on the principle of agreement aperture and field angle of the optical system and the possibility of converting the transverse dimensions of the cylindrical light tubes by using the afocal optical system. In general, the task of converting a formed cylindrical light tube with the desired dimensions in the reverse path of the rays can be solved with a help of the single afocal system consisting of two positive components. In paper some variants of the optical system scheme for preliminary (initial) conversion of light tubes with an indication of their main advantages and disadvantages are presented. Aberration analysis of optical systems was carried out.
