Tanks and armoured vehicles use periscopes: they enable drivers, tank commanders, and other vehicle occupants to inspect their situation through the vehicle roof. Prior to periscopes, direct vision slits were cut in the armour for occupants to see out. Periscopes permit view outside of the vehicle without needing to cut these weaker vision openings in the front and side armour, better protecting the vehicle and occupants.

In this context a periscope refers to a device that can rotate to provide a wider field of view (or is fixed into an assembly that can), while an episcope is fixed into position. As of 2009 [update] modern submarine periscopes incorporate lenses for magnification and function as telescopes. They typically employ prisms and total internal reflection instead of mirrors, because prisms, which do not require coatings on the reflecting surface, are much more rugged than mirrors. They may have additional optical capabilities such as range-finding and targeting. The mechanical systems of submarine periscopes typically use hydraulics and need to be quite sturdy to withstand the drag through water. The periscope chassis may also support a radio or radar antenna.Kastrenakes, Jacob (31 March 2021). "Periscope shuts down, six years after popularizing mobile live streaming". The Verge .

In its simplest form, it consists of an outer case with mirrors at each end set parallel to each other at a 45° angle. This form of periscope, with the addition of two simple lenses, served for observation purposes in the trenches during World War I. Military personnel also use periscopes in some gun turrets and in armoured vehicles. [1] The first implementation of the Periscope Lens in smartphones was done by Huawei which introduced the 5x optical zoom. However, many argue that Sharp 902 which launched around 2002 was arguably the first phone to feature a Periscope Lens-like setup with 2x optical zoom using a single lens. Later Samsung also introduced the Periscope Lens with Galaxy S20 Ultra, the company calls it Space Zoom. Do you have a friend who’s 200-cm or 6’6” tall?
