Extended iris control for image blending in a stereomicroscope

Medical stereo microscope has a main objective (10) and left and right main beam paths (2a, 2b). In at least one of the main beam paths a switchable shutter is provided (18a, 18b) between the output reflecting beam splitter (12a, 12b) and the main observation output (21a, 21b). Further an input refl...

Beschreibung
Zusammenfassung:	Medical stereo microscope has a main objective (10) and left and right main beam paths (2a, 2b). In at least one of the main beam paths a switchable shutter is provided (18a, 18b) between the output reflecting beam splitter (12a, 12b) and the main observation output (21a, 21b). Further an input reflecting beam splitter (11a, 11b) prior to the output beam splitter with corresponding shutters (17a, 17b). Light from the input reflecting beam splitter is collected in an auxiliary observation output (20a, 20b). Additional information or images are provided from a source (16) that is linked into the observation beam paths via a switchable deflection prism (14).
