Scopes

Scopes make distant objects appear larger and, thus, easier to view. Scopes come in a wide variety of sizes and magnifications, from small handheld hiking and night-vision scopes to observatory-sized astronomical telescopes. Spyglasses are simple scopes, like those pictured in paintings of historic mariners, especially pirates and explorers. Binoculars are two scopes combined side-by-side to provide magnification for both eyes. Periscopes are viewing scopes used in submarines. Microscopes, which magnify tiny objects, are important laboratory tools, especially in the forensic sciences.
