capabilities of the instrument. The number before the "x" represents the magnification power‚ while the number after the letter represents the aperture (or diameter) of the objective lens in millimeters. So a 8x35 binocular‚ for example‚ features a 35 mm lens and can make objects appear eight times closer to you. A 10x50 lens brings things 10 times closer. Dividing the second number by the first produces the value of the exit pupil‚ or the diameter of the light beam which reaches the eye in millimeters
