kiikaritähtäin

A kiikaritähtäin, commonly known as a telescopic sight or scope, is an optical sighting device that uses a system of lenses to provide a magnified image of a distant target. This magnification allows a shooter to aim more accurately than with open sights. The primary components of a kiikaritähtäin include an objective lens, an erector lens system, an eyepiece, and a reticle.

The objective lens gathers light from the target and forms an initial image. The erector system then inverts and magnifies this image, and the eyepiece allows the user to view the magnified, upright image. The reticle, often a crosshair or a more complex pattern, is located within the scope and appears superimposed on the target image, providing a precise aiming point.

Kiikaritähtäimet are widely used in various shooting disciplines, including hunting, sport shooting, and military applications. They are characterized by their magnification, measured in power (e.g., 4x, 9x), and the diameter of the objective lens, which influences light gathering capability (e.g., 32mm, 40mm). Adjustable turrets on the scope allow for windage and elevation adjustments to compensate for bullet drop and wind drift. The development of kiikaritähtäimet has significantly contributed to the precision and effectiveness of modern firearms.
