An optical system or display is orthostereoscopic when it reproduces the exact depth, scale, and spatial relationships of the original scene. This requires the viewing geometry to perfectly match the capture geometry, meaning the interpupillary distance and focal lengths align exactly. Engineers aim for this condition in VR headsets and binocular optics to prevent eye strain and spatial disorientation.

The new binocular microscope is fully orthostereoscopic, so operators can manipulate tiny components without misjudging depth.
