Technical Features

Posted in News on February 4th, 2014

This is a very important feature of the binoculars. The larger the lens, the greater the aperture, it has, that is, the more light passes, and respectively, gives a vivid and detailed images. In addition, the larger the lens, the greater the angle of view. But the size of the device are directly dependent on the diameter of the lens (the larger it is, the greater the weight and size of binoculars). We compare characteristics of the models nikon Action 7×50 cf and nikon Action 16×50 cf. For the same diameter lens and different multiplicity obtained significant differences in the basic parameters of 'angle', 'view' and 'relative brightness': Technical Features: 7358x407x5010x5012x5016x50, times 787101216Diametr lens mm.354050505050Ugol of view (Real / degree). of visibility, hail. 65.165.644.865.066.065.6Pole of view at 1,000 m pupil, mm Relative brightness Exit Pupil, mm 11.911.917.611.89.712.3Minimalnoe Dist. focusing m5. interpupillary distance, mm56-7256-7256-7256-7256-7256-72Ves, Mr. 715760980970960990Dlina mm 123143189184179184Shirina mm 182182193193193193 type PorroPorroPorroPorroPorroPorro angle of view – directly to the angle of view with which you can see the image (Characterizes the dimensions of space, which can be seen in the stationary binoculars). In general, the greater the angle of view, the more evident.

The angle of view is also often marked on the binoculars' body (specified in degrees). Field of view – this parameter can be found in the technical specifications of binoculars. It is not indicated on the binoculars' body, but mention it because, in principle, it is the same, the angle of view, but it's easier – the width of the image visible object in meters, located on you at a distance of 1000 meters.
