PROBLEM TO BE SOLVED: To provide an optical system suitable for use in surgical microscopes.SOLUTION: The present invention relates to an optical system for imaging an object region (12) with an optical beam path (16r, 16r') in image planes (27a, 27b, 27c) of an image capturing system. The optical system includes a first optical assembly (18) through which the optical beam path (16r) passes, and a second optical assembly (24) arranged in the optical beam path (16r) on the side of the first optical assembly (18) facing away from the object region (12). According to the present invention, the second optical assembly (24) is a system for at least partially correcting longitudinal chromatic aberration of the first optical assembly (18) occurring in a wavelength range of 625 nm≤λ≤850 nm of the light.SELECTED DRAWING: Figure 1 【課題】手術用顕微鏡での使用に適した光学系を開発する。【解決手段】本発明は、対象部位（１２）を光ビーム路（１６ｒ、１６ｒ'）によって撮像系の像面（２７ａ、２７ｂ、２７ｃ）に結像するための光学系に関する。光学系は、光ビーム路（１６ｒ）が通過する第１の光学部品（１８）と、対象部位（１２）とは反対の第１の光学部品（１８）の側の光ビーム路（１６ｒ）に配置された第２の光学部品（２４）と、を含む。本発明によれば、第２の光学部品（２４）は、光の波長領域６２５ｎｍ≦λ≦８５０ｎｍで生じる第１の光学部品（１８）の縦色収差を少なくとも部分的に補正する系として構成される。【選択図】図１
