The Sussex Astronomy Centre


Binoculars are handheld optical instruments that use two small telescopes, one for each eye, to magnify distant objects. They are widely used for a variety of purposes, including bird watching, astronomy and sports events.

Binoculars consist of a pair of lenses that collect and focus light, and prisms that bend and redirect the light to the eyepieces. The prisms serve to correct the orientation of the image, allowing the observer to see the object right-side up and in the correct orientation.

Binoculars are classified by their magnification and objective lens diameter. For example, a pair of binoculars with a magnification of 10x and an objective lens diameter of 42mm is often referred to as "10x42" binoculars. The magnification indicates how much closer the object appears through the binoculars compared to the naked eye, while the objective lens diameter determines the amount of light that the binoculars can gather.

The use of ED glass greatly reduces a visual defect known as chromatic aberration. This is essentially the colour fringing that appears when looking through a pair of binoculars which can distort the true image. Binoculars which use ED glass (see below) are able to stop this from happening.
