Binoculars are pair of mirror balanced microscope
Binoculars mainly come in two designs:
Galilean Binoculars :- It is the oldest binoculars manufactured in17 century used Galilean optics so it was called Galilean Binoculars. In this optical instrument a convex object and concave lens were used. It has the advantage of presenting vertical images but another side have drawback also, it was not capable of high magnification as of its narrow field of view. Still Galilean models are used in some places like Opera house, theatre house and in some Cheap Binoculars .
Prism Binoculars :- To overcome from the drawback of high magnification in Galilean Binoculars, the Carl Zeiss Company has manufactured the prism Binoculars in eighteen century. It has the feature of folding the optical path thus Physical length of binocular is less than the focal length and space of Object. Thus the length of such type of optical instrument has reduced.
Optical parameters :- Optical instruments are generally designed for particular application for which they are planned. It comes in some certain optical parameters like magnification, objective diameter field of view, Eye relief and close focus distance.
Best two brands of market :- Nikon is an optical apparatus use for different uses like for Hunting, Astronomy, Tracking, Opera and Theatre, Camping, Outdoor festival or watching any sport event etc. It give users a three-dimensional image like telescope ; for nearer objects the two views, presented to each of the viewer's eyes from slightly different viewpoints, produce a compound view with an impression of depth.
Bosma are one of the very important apparatus of tracking, when you go out for hunting, a camping or any other activity in al fresco. It has so many fastidious applications which helps the user to visualize object from a far and the first thing that this tool have is the magnification. The magnification is the ability of the object to focus the focal length and makes the object closer.
Conclusion :- An optical instrument give users a three-dimensional image like telescope for nearer objects the two views, presented to each of the viewer's eyes from slightly different viewpoints, produce a compound view with an impression of depth. Nikon binocular is one of the best viewing objects in the mount of Binoculars.
