Construction of Binoculars in short
Answers
The basic binocular uses a convex objective and a concave eyepiece lens. This is also known as Galilean optics.
Binoculars, followed the invention of telescope in the 17th century. The basic model of a binocular consists of two telescopes mounted side by side for optimum binocular vision.
Binocular vision is three-dimensional vision of an object, by using two eyes. In common terms, binocular is an instrument used to get clear, enlarged view of objects which are far.
Also known as field glasses or binocular telescopes, binoculars are a pair of mirror symmetrical telescopes that allow a user to view distant objects using both eyes. To allow both eyes to view distant objects symmetrically, the binoculars require two separate telescopes, one for each eye, held together in the device called binoculars allowing binocular vision. The telescopes are mounted symmetrically side-by-side and aligned to point accurately in the same direction, providing the user with undistorted vision of distant objects.
