PERISCOPIC LENS Meaning and
Definition
-
A periscopic lens is an optical device used in various fields, particularly in photography and videography, which allows for a unique viewing perspective by reflecting or refracting light. The term periscopic is derived from the Greek words peri, meaning "around," and scope, meaning "to look or observe." This type of lens resembles a periscope, a device used in submarines to enable individuals to see above the surface of the water.
A periscopic lens consists of a series of mirrors or prisms strategically arranged to redirect the light passing through it, resulting in an altered line of sight. The purpose of this lens is to provide a viewing angle that is different from the typical straight-on perspective. By manipulating the direction of the light, the periscopic lens widens the field of view, allowing for a broader and more encompassing observation.
In the context of photography and videography, a periscopic lens is often used to capture images or footage from unique angles or perspectives that would be otherwise challenging or impossible to achieve. It enables photographers and cinematographers to shoot from lower or higher vantage points without compromising image quality. This type of lens is frequently employed in sports photography, documentary filmmaking, and architectural photography.
Overall, a periscopic lens provides a versatile and creative tool for visual arts, allowing for innovative compositions and an unconventional way of perceiving the world.

Etymology of PERISCOPIC LENS
The word "periscopic" is derived from the combination of two Greek roots: "peri" meaning "around" or "surrounding" and "skopos" meaning "to look" or "to see".
The term "periscopic" is used to describe an optical instrument or lens system that enables observation or viewing from different angles or perspectives. The "periscopic lens" specifically refers to a lens that allows for the viewing or photographing of objects above or below the line of direct sight, such as in periscopes or certain types of cameras.
