Embodiment Construction

[0039] First, refer to figure 1 The design and function of the illumination and observation system 1 in the microscope 2 are explained. figure 1 A schematic plan view of the main objective 3 with a first observation pupil 4 and a second observation pupil 5 is shown. The first observation pupil 4 and the second observation pupil 5 are preferably used to assist eg an assistant or student in ophthalmic surgery.

[0040] The on-axis illumination 6 is directed through the first observation pupil 4 , while the main illumination 7 is directed through the second observation pupil 5 . Preferably, there is no overlap of the primary illumination with the first observation pupil 4 and / or no coaxial illumination in the second observation pupil 5 .

[0041] figure 1 The setup shown is particularly useful for microscopes 2 used in ophthalmic surgery, so-called ophthalmic microscopes. At the object to be observed, ie in the object plane, the main illumination 7 produces an illumination fi...

Abstract

The invention relates to an Illumination and observation system (1), in particular for an ophthalmic microscope. The system comprises a first observation pupil (4) and a second observation pupil (5) for the eyes of an observer such as an assistant. Further, the system comprises a coaxial illumination (6) in the first observation pupil (4) and a main illumination (7), the coaxial illumination (6) being adapted to generate a red reflex (13) in the observed eye in operation and the main illumination having a larger field of illumination than the coaxial illumination (6, 10, 11). In order to facilitate usage of the system (1) and / or the microscope (2) and to create a superior stereoscopic view using the red reflex (13), a control subsystem (21, 27) is provided which is adapted to automaticallyadjust an intensity of the main illumination (7) depending on a change in an intensity of the coaxial illumination (6).

Description

technical field [0001] The present invention relates to an illumination and observation system for a microscope, in particular for performing ophthalmic surgery, wherein the system comprises a first observation pupil and a second observation pupil for the eyes of an observer (e.g. an assistant) , and coaxial illumination in the first viewing pupil adapted to produce a red reflection in the observed eye when in operation. [0002] The invention also relates to a microscope, in particular a microscope for ophthalmic surgery comprising such a system. Finally, the invention relates to a method of microscopy by using coaxial illumination to illuminate an object coaxially through the first observation pupil and by using primary illumination to illuminate a larger field of illumination in the object plane than the coaxial illumination to illuminate the object. Background technique [0003] Ophthalmic microscopes, i.e. microscopes used in eye surgery, typically include two differe...
