    摘要: A method is disclosed for fixing at least one location in an examination field (9) with respect to a coordinate system (13). The method includes determining, in response to a request (65), coordinates of a first location (59) as a first coordinate set (x, y, z) allocated to the first location (59). A first recording and a second recording of topological data (69) in a spatially extended area around the first location (59) in the examination field (9) are obtained. The first and second recordings are compared to determine a displacement (&Dgr;x, &Dgr;y, &Dgr;z) of the first location (59) of the examination field (9) with respect to the coordinate system (13), the coordinates of the first coordinate set (x, y, z) allocated to the first location (59) are changed dependent upon the determined displacement (&Dgr;x, &Dgr;y, &Dgr;z) such that the changed coordinates substantially correspond to the coordinates of the first location (59) in the examination field (9) after the displacement thereof.

    摘要: An ophthalmic surgical microscope (100) has a microscope main objective (101) and a viewing beam path (105) which passes through the microscope main objective (101) for visualizing an object region. The ophthalmic surgical microscope (100) includes an OCT-system (140) for recording images of the object region (108). The OCT-system (140) includes an OCT-scanning beam (142) which is guided via a scan mirror arrangement (146) to the object region (108). An optic element (147) is provided between the scan mirror arrangement (146) and the microscope main objective (101). This optic element (147) bundles the OCT-scanning radiation exiting from the scan mirror arrangement (146) and transfers the same into a beam path which passes through the microscope main objective (101). Alternatively or in addition, the ophthalmic surgical microscope (100) includes an ophthalmoscopic magnifier lens (132) which can be pivoted into and out of the viewing beam path (105) and the OCT-scanning beam (142).

    摘要: A surgical microscope (100) has an illuminating module (120). The illuminating module contains an illuminating optic which images a field diaphragm (124) to a parallel illuminating beam path at infinity. The field diaphragm (124) is illuminated by a light source. The illuminating optic includes a first lens assembly and a second lens assembly which functions to image the field diaphragm (124) into the object region (108) via the microscope main objective (101) of the surgical microscope (100). An in-coupling element (128) is provided between the first lens assembly (125) and the second lens assembly (126) and this in-coupling element couples the OCT-scanning beam into the illuminating beam.
