Magnification is the degree to which the object being viewed is enlarged, and is designated on binoculars as the number preceding the "x." For example, when using an 8x42 binocular, 8x represents the binocular's magnification. An 8x magnifies an image to eight times the size it would be when viewed by the normal, unaided human eye. Similarly, a 15x70 binocular magnifies an image 15 times, and so on.

Linearlypolarized light

Light waves are transverse: that is, the vibrating electric vector associated with each wave is perpendicular to the direction of propagation. A beam of unpolarized light consists of waves moving in the same direction with their electric vectors pointed in random orientations about the axis of propagation. Plane polarized light consists of waves in which the direction of vibration is the same for all waves. In circular polarization the electric vector rotates about the direction of propagation as the wave progresses. Light may be polarized by reflection or by passing it through filters, such as certain crystals, that transmit vibration in one plane but not in others.

The objective lenses of binoculars are the front lenses. The diameter of one of these lenses, given in millimeters, will be the second number describing a particular binocular. Hence, a 7x42 binocular has an objective lens of 42mm.  The diameter of the lens determines the light gathering ability of the instrument, with the greater light gathering ability of a larger lens translating into greater detail and image clarity. This is especially useful in low light conditions and at night. Doubling the size of the objective lenses quadruples the light gathering ability of the binocular. For instance, a 7x50 binocular has almost twice the light gathering ability of a 7x35 binocular and four times the light gathering ability of a 7x25 binocular. This might lead you to assume that bigger is better when it comes to the diameter size of the objective lenses. In reality the size of the lens must be considered along with exit pupil and intended usage to determine the best binocular for your personal use.

Binocular size is defined by its magnification and objective, but if you are new to the hobby, what do these mean when observing. Below we have how to identify these two and how it effects your viewing.
