Introduced is an optical arrangement for varying an imaging ratio and/or a refractive power including at least one optical axis, having at least two optical elements, which can be pivoted into and/or pivoted to and/or switched into and/or switched to the optical path, which encompass in each case a refractive power and an optical axis and the optical axes of which can in each case be made to be substantially congruent with the optical axis of the arrangement or are substantially congruent with the optical axis of the arrangement. The optical path between the optical elements, which can be pivoted into and/or pivoted to and/or switched into and/or switched to, undergoes at least one change in direction and/or vergence. |
