Explanations for choosing the right binocular magnification The magnification of a binocular model is perhaps the most misunderstood feature. High magnification can be useful! However, magnification in itself is by no means a criterion for the quality, image quality or detail recognition capability of binoculars! The "first" number (e.g. 10x..) of an optical system stands for the magnification. With a 10x [...]
Influence of objective lens diameter on the light intensity of the binoculars or on the objective lens light intensity The "second" figure (e.g. ..x50) indicates the diameter of the front lens of the objective lens (usually the larger diameter) in mm. The larger this is, the more light can be absorbed by the lens of the optical system. While a lens diameter of 20mm is sufficient during the day [...]
Calculation of twilight number and statement on twilight performance for binoculars The visual acuity of the human eye decreases in twilight to around a third of daytime visual acuity. The eye's sensitivity only increases for the blue spectral range. In order to be able to recognise details over long distances in twilight, binoculars with high magnification and corresponding [...]
Exit pupil of binoculars - meaning and calculation In addition to the twilight number, the exit pupil at the eyepiece of the binoculars is also very important for seeing in twilight (twilight vision). In theory, the larger the diameter of the exit pupil, the greater the image brightness in the eye. Calculating the exit pupil To determine the binocular exit pupil, calculate the ratio of the binocular magnification to the objective lens diameter: For 8x56 binoculars, calculate the [...]
Binoculars and riflescopes Field of view and angle of view The field of view of binoculars or riflescopes is specified either in degrees (angle of view) or in metres. The size of the field of view indicates the width of the terrain that can be observed through the binoculars at a distance of 1000 metres. In contrast, the field of view of riflescopes is usually specified for distances of 100 metres. Binoculars without a wide-angle function have a [...]
