Answer Details
The device that does not use plane mirrors in its operation is binoculars. A periscope uses two plane mirrors to reflect light and allow a person to see over an obstacle or around a corner. A sextant uses a plane mirror to reflect the image of the sun or stars onto a scale, enabling sailors to navigate. A kaleidoscope uses multiple plane mirrors to reflect and multiply the image of small colored objects into a visually attractive pattern. However, binoculars use a combination of convex and concave lenses to magnify distant objects, rather than plane mirrors.
