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 polarizer, a display device configured to present an image of a surgical scene, and 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. The first polarizer in the lens assembly is configured such that light reflected from the reflective surface passes through the first polarizer, and light reaching the first polarizer without being reflected from the reflective surface is substantially blocked.
