Principle of light refraction

To understand how a monocular works, it’s important to grasp the principle of light refraction. When light passes through a lens, it bends or refracts, allowing the lens to focus the incoming light rays. This bending effect is what enables a monocular to magnify objects. By manipulating the shape and curvature of the lens, monoculars can alter the path of light, resulting in a magnified and clearer image.

How the monocular magnifies the image

A monocular achieves magnification by using a combination of lenses. The objective lens gathers the light and directs it towards the eyepiece. Within the eyepiece, additional lenses further magnify the image, allowing it to appear larger and closer than it actually is. The overall magnification power of a monocular is determined by the ratio of the focal lengths of the objective lens to the eyepiece. It is important to note that while magnification brings distant objects closer, it also narrows the field of view.
