Binoculars for Travel

Many people who travel use binoculars. Binoculars are particularly useful in adventure travel, such as traveling to national parks or safaris, where the traveler might want to view wildlife. Binoculars get you closer to the object you are studying without needing to be physically closer. Travel binoculars are usually lighter and more compact than traditional binoculars. They easily fit in a carry on bag, and some are small enough to fit in a pocket. Often travel binoculars come with a case that can clip on to the belt for easy carrying when on a trip.

Components of Travel Binoculars

Before choosing binoculars, you need to know a little about how all binoculars work.

Prism

All binoculars have prisms, which are the component that allow you to see the image right-side-up when looking through the binoculars. Travel binoculars usually have roof prisms, which are contained inside the optical tube of the binoculars. This saves space in the binoculars, which make it great for travel.

Lens Coating

Binocular lenses are coated on the glass surfaces that touch the outside air. The coating helps transmit the light. Look for binoculars that are fully coated, as this means that all of the exposed glass is coated. Also, look for binoculars that are multi-coated, which means that there are several layers of coating. This helps to reduce glare.

Magnification and Objective Lenses

Magnification is the power of the binoculars. Magnification is usually stated in two numbers, such as 8 x 25. The first number means how much the binoculars magnify an object. An 8x magnification means that the object looks eight times closer than natural eyesight. The second number is the objective lens diameter. The smaller the diameter, the more compact your binoculars are for travel. However, the larger the diameter, the more light you will have entering your binoculars. The objective lens is the lens that faces the object.

Exit Pupil

The exit pupil is the lens by your eye. If you hold the binoculars at arms length, you will see a small spot of light through the eyepieces. This is the exit pupil.

Field of View

You will have a limited field of view, which is the area you can see when looking through your binoculars. This area is measured in degrees. If you are going to be watching moving objects, look for a large field of view.
