Assignee: CARL ZEISS MEDITEC AG
Field: Optics (Instruments)
Classification: CPC G  A | IPC A  G

Claim 0:
1. A visualization system for observing a surgical site (OP site) in an operating environment
having a head-mounted visualization unit,
having an at least partially light-transmissive optical system,
wherein the optical system has a first optical channel, which is assigned to a first eye of a user of the head-mounted visualization unit, and a second optical channel, which is assigned to a second eye of the user,
wherein the first optical channel is substantially transmissive to optical radiation of a first polarization and substantially opaque to optical radiation of a second polarization, with the first polarization being substantially orthogonal to the second polarization,
wherein the second optical channel is substantially transmissive to optical radiation of the second polarization and substantially opaque to optical radiation of the first polarization,
wherein a polarizer and a light attenuator are arranged at least in the first optical channel, and
wherein the light attenuator is arranged downstream of the polarizer in a direction toward the first eye of the user, and
having a screen, wherein the screen is set up to present a first image of the OP site with the first polarization and a second image of the OP site with the second polarization for stereoscopically reproducing a sample image.
