Origin of 'periscope'

The word 'periscope' originates from the Greek words 'peri,' meaning 'around,' and 'scope,' meaning 'to look or examine.' The term began to be used in the 19th century, particularly in relation to submarine technology. Early designs were simple and consisted of two mirrors positioned at an angle to direct light from the surface down into the submarine. Over time, the design evolved, incorporating prisms and additional lenses for improved visibility. The periscope became a critical tool in naval warfare, allowing submarines to remain submerged while still gathering information about enemy ships and activities above water. Its use extended beyond military applications into civilian domains, including education and recreational activities, showcasing the versatility of this ingenious optical device.
