| 摘要 |
The invention relates to an eyepiece device (20), an eyepiece (44) and a surgical instrument (2), wherein the eyepiece device (20) for a surgical instrument (2) comprises an eyepiece frame (22) and at least one optical unit (24), wherein the optical unit (24) is accommodated in the eyepiece frame (22). The optical unit (24) comprises a first optical element (26) and a second optical element (28) connected therewith, wherein the optical elements (26, 28) form an optical unit (24) which is corrected in respect of chromatic aberration and the second optical element (28) is produced from a material with abnormal dispersion. The eyepiece device (20) is developed by virtue of there being at least one mechanical connection element (30) between the eyepiece frame (22) and the first optical element (26) for accommodating the optical unit (24) in the eyepiece frame (22). |
