Specifications of Binoculars

When choosing binoculars, there are several considerations that every buyer should make. This is done in order to get the one that suits your needs. If you are a first timer and not yet sure what to buy, here is a simple guide that you can follow:

  • Magnification

In simple terms, this is likely referring to the size of an object as compared to what a viewer see with the naked eye. If the binoculars have higher magnification, the more unstable the image can be due to movements. For general use, binoculars with 12x magnification are recommended.

  • Brightness and Exit Pupil

This refers to the circle seen at the center of the eyepiece. This appears when holding the binoculars 30 cm away from the eyes, while the lenses are pointing into a bright light. When buying binoculars, remember that the one with a bigger diameter can give a brighter image view.

  • Apparent Field of View

This refers to the angle of the magnified field when using binoculars. If your binoculars’ apparent field of view is larger, the wider field of view you will see even with high magnifications.

  • Eye Relief

This refers to the position where the exit pupil is created. In simple terms, it is the distance formed starting from the outer surface of the lens until the eye point. If you are wearing eyeglasses, you will be able to view without removing your eyeglasses at 15mm or longer.

  • Effective Diameter of the Objective Lens

This is the diameter found inside the objective lens frame. The effective diameter for compact type is below 25mm, 30-49 for standard and over 50mm for business use and astronomical observation.

  • Rear Field of View

This refers to the angle of the visible field view without making any movements with the device. This is being measured starting from the central point of the objective lens. If you want to get wider view, your binoculars should be of greater value.

  • Close Focusing Distance

This determines the distance to the nearest point that can be focused. This is responsible in making far objects look nearer. The minimum focusing distance is at 1-2 meters.
