Periscope vs. Binocular — What's the Difference?

Can be simple or complex depending on the application.

Often used in bird watching, sports, and astronomy.

Does not typically include magnification features.

A pair of telescopes mounted side-by-side, adjusted to point in the same direction.

A device consisting of mirrors or prisms for viewing over, around, or through an obstacle.

Includes features like zoom and focus for enhanced viewing.

An optical instrument for observation from a concealed position.

Portable and designed for outdoor use.

A periscope is an instrument for observation over, around or through an object, obstacle or condition that prevents direct line-of-sight observation from an observer's current position.In its simplest form, it consists of an outer case with mirrors at each end set parallel to each other at a 45° angle. This form of periscope, with the addition of two simple lenses, served for observation purposes in the trenches during World War I. Military personnel also use periscopes in some gun turrets and in armoured vehicles.More complex periscopes using prisms or advanced fiber optics instead of mirrors and providing magnification operate on submarines and in various fields of science.

Optical devices using lenses and prisms to view distant objects.

Used primarily in military applications to observe from protected positions.

Having two eyes arranged to produce stereoscopic vision.

An apparatus consisting of a tube attached to a set of mirrors or prisms, by which an observer (typically in a submerged submarine or behind a high obstacle) can see things that are otherwise out of sight.

OftenbinocularsAn optical device, such as a pair of field glasses or opera glasses, designed for simultaneous use by both eyes and consisting of two small telescopes joined together.

Any of various tubular optical instruments that conn reflecting elements, such as mirrors and prisms, to permit observation from a position displaced from a direct line of sight.

Using two eyes or viewpoints; especially, using two eyes or viewpoints to ascertain distance.

A form of viewing device that allows the viewer to see things at a different height level and usually with minimal visibility.

Attributive form of binoculars

(obsolete): A general or comprehensive view.

Relating to, used by, or involving both eyes at the same time:binocular vision.

(intransitive) To rise and peer around, in the manner of a periscope.

A pair of binoculars.

A general or comprehensive view.

(dated) Any binocular glass, such as an opera glass, telescope, or microscope.

An optical instrument of tubular shape containing an arrangement of lenses and mirrors (or prisms), allowing a person to observe a field of view otherwise obstructed, as beyond an obstructing object or (as in submarines) above the surface of the water.

Having two eyes.

An optical instrument that provides a view of an otherwise obstructed field

Pertaining to both eyes; employing both eyes at once; as, binocular vision.

Adapted to the use of both eyes; as, a binocular microscope or telescope.

A binocular glass, whether opera glass, telescope, or microscope.

An optical instrument designed for simultaneous use by both eyes

Relating to both eyes;

No, periscopes are also used in tanks and can be found in some science kits for educational purposes.

Magnification in binoculars is achieved through a series of lenses and prisms that enlarge the image of distant objects.

Typical magnifications range from 5x to 20x, depending on the model.

Yes, there are specific models of binoculars designed for night vision.

Yes, many high-powered binoculars can be mounted on tripods for stable viewing.

The main advantage is the ability to observe from behind cover, providing safety and concealment.

Standard binoculars can weigh from less than a pound to several pounds, depending on their size and build.

Periscopes are less portable than binoculars, which are specifically designed for easy transport and use.

Most basic periscopes use mirrors, but more complex designs might use prisms.

Generally, periscopes are designed specifically for viewing, though creative adaptations might include measurement scales.

Yes, many binoculars are designed to be waterproof and fog-proof, especially for outdoor activities.

Periscopes are usually made from durable materials like metal and sometimes reinforced plastics.

Yes, modern binoculars usually come with easy-to-use focusing mechanisms.

Basic periscopes can be quite inexpensive, while binoculars can range widely depending on features and quality.

Binoculars typically have a wider field of view than periscopes.
