Abstract (en)
[origin: WO2007082691A2] The invention relates to a stereoscopic optical system (1) which comprises a first optical subsystem (2L) with a plurality of optical elements (4L-12L) for providing a left-hand imaging beam path (14L) of the stereoscopic optical system (1) and a second optical subsystem (2R) with a plurality of optical elements (4R-12R) for providing a right-hand imaging beam path (14R) of the stereoscopic optical system (1). The first optical subsystem (2L) has a least one first optical lens (4L) with a first optical surface (15L) which constitutes a partial surface of a first rotationally symmetric mathematical surface (31) in the area of the left-hand imaging beam path (14L). Said first mathematical surface (31) has a first maximum radius (R1) in relation to a first axis of symmetry (16L). The second optical subsystem (2R) has a least one second optical lens (4R) with a second optical surface (15R) which constitutes a partial surface of a second rotationally symmetric mathematical surface (31) in the area of the right-hand imaging beam path (14R). Said second mathematical surface (31) has a second maximum radius (R2) in relation to a second axis of symmetry (16R). The first optical lens (4L) is a first off-axis lens (4L) whose first center of gravity (17L) of its first surface (15L) has a distance (AL) from the first axis of symmetry (16L) of the first mathematical surface (31), which is greater than 0.2 times the first maximum radius (R1) of the first mathematical surface (31). The second optical lens (4R) is a second off-axis lens (4R) whose second center of gravity (17R) of its second surface (15R) has a distance (AR) from the second axis of symmetry (16R) of the second mathematical surface (31), which is greater than 0.2 times the second maximum radius (R2) of the second mathematical surface (31). The invention also relates to a stereoscopic optical system which is multiply folded by means of deflection elements. The invention finally relates to a headset magnifier and to a surgical microscope into which the stereoscopic optical system is integrated.
