telescopic sight

A telescopic sight is an optical device used to aid in aiming a firearm. It functions like a small telescope, magnifying the target to improve accuracy. These sights consist of lenses that refract light, allowing the user to see a clearer, larger image of the distant target.

The earliest forms of aiming devices for firearms date back to the 15th century, evolving from simple iron sights to more complex optical systems. Telescopic sights specifically emerged in the 17th century and saw increased use in military applications, such as by snipers in the U.S. Civil War and World War I. Modern advancements have led to a wide variety of telescopic sights with different powers of magnification, and some are even designed for low-light conditions.12
