Abstract: The technology described in this document can be embodied in a viewing apparatus for a surgical device, the apparatus including a lens assembly including a first circular polarizer, a display device configured to present an image of a scene, a reflective surface oriented at an acute angle with respect to the display device such that light from the display device is reflected from the reflective surface towards the lens assembly, and a second circular polarizer configured to impart a circular polarization to the light from the display device. The first polarizer in the lens assembly is configured such that light reflected from the reflective surface passes through the first circular polarizer, and line-of-sight light reaching the first circular polarizer without being reflected from the reflective surface is substantially blocked.
