Parameter interpretation of binoculars
1) Specification: The specification of binoculars is represented by the "magnification ×objective diameter"
2) Magnification: The magnification of binoculars means the ability to observe closely the object.
3) Objective diameter: The objective diameter is the optical aperture of binoculars, which is the channel of the external light entering the telescope.
4) Field:Field is the field of view, generally using"... M/1000M or"... Degree “ as representation. In general, Edge imaging of binoculars with large field is inferior to the binoculars with small field’s, which is basically a contradiction.
5) Exit Pupil: The Exit Pupil is the spot size which is formed by the image through the binoculars eyepiece, a simple formula: objective diameter / magnification = Exit Pupil.
6) Eye relief: Exit relief refers to the longest distance of the eyes away from the eyepiece when you see clearly the whole field.
7) Lightness, also called as Brightness is the brightness of binoculars imaging.
8) Close quarter:the close quarter is the closest distance between a person and imaged objective which is observed by binoculars. That is the binoculars' shortest focusing distance.
