    en.wikipedia.org/wiki/Binoculars

    Hand-held binoculars range from small 3 × 10 Galilean opera glasses, used in theaters, to glasses with 7 to 12 times magnification and 30 to 50 mm diameter objectives for typical outdoor use.

    A Fresnel lens ( / ˈfreɪnɛl, - nəl / FRAY-nel, -⁠nəl; / ˈfrɛnɛl, - əl / FREN-el, -⁠əl; or / freɪˈnɛl / fray-NEL [1]) is a type of composite compact lens which reduces the amount of material required compared to a conventional lens by dividing the lens into a set of concentric annular sections.

  4. Loupe - Wikipedia

    en.wikipedia.org/wiki/Loupe

    Diagram of a single lens loupe. Three basic types of loupes exist: Simple lenses, generally used for low-magnification designs because of high optical aberration. Compound lenses, generally used for higher magnifications to control optical aberration. Prismatic, multiple lenses with prisms. [2]

    Magnification. An Elcan SpecterOS 4x prism sight with a Shield Sights reflex sight mounted on top. Prism sights often have fixed low-power magnification such as 1× (parity magnification or "non-magnifying"), 2×, 3× or 4x magnifications, sometimes 5× or more.

  6. Monocular - Wikipedia

    1 – Objective lens 2 – Schmidt-Pechan prism 3 – Eyepiece. A monocular is a compact refracting telescope used to magnify images of distant objects, typically using an optical prism to ensure an erect image, instead of using relay lenses like most telescopic sights.

  7. Telescopic sight - Wikipedia

    en.wikipedia.org/wiki/Telescopic_sight

    Telescopic sights are used with all types of systems that require magnification in addition to reliable visual aiming, as opposed to non-magnifying iron sights, reflector (reflex) sights, holographic sights or laser sights, and are most commonly found on long-barrel firearms, particularly rifles, usually via a scope mount.
