Binoculars are simply two telescopes strapped together, one for each eye. Whilst this limits them in some areas such as range, it allows the viewer to effectively judge distance. This is because to be able to judge distance, a person needs both eyes to view the object, which traditional astronomical telescopes do not do. Socially, binoculars are used mainly for bird watching, and they are the perfect tool to help you to do this. They are generally light weight, and easy to use.
Binoculars work on the principle of a reflector telescope. This means that instead of a traditional straight lens, binoculars have mirrors inside them which help to gather light. This all adds up for quality of image when viewing through the binocular.
With technology taking a presence in all fields of life, new high-tech binocular technology has changed the way that hand-held binoculars work. Some binoculars can now offer image stabilisation, allowing the viewer to view a desired moving target with extra confidence. This image stabilisation generally works by having gyroscopes mounted within the binoculars to stable the inevitable shaky movements. However, some disadvantages also come with this technology. Mainly, this regards the quality of image. The quality of image from a binocular fastened to a tripod will not be as good as expected. Also, these high tech binoculars tend to be more expensive, and heavier.
New technologies are revolutionising the way binoculars function. With this new technology generally comes expense, but it is well worth it. Modern binoculars can come with an array of specification, with extras such as Anti-Fog viewing.
