We need to consider certain points during purchasing a binocular. The potential buyer is faced with a countless of options and ultimately would be left in more confused state. If your not familiar with the technical aspect of the binoculars. I hope this article would provide some of it.The outer appearance of the binocular would catch your first glance. Are basic design, central focusing knob/wheel and diopter(A unit of measurement of the refractive power of a lens which is equal to the reciprocal of the focal length measured in meters; used by oculists)

The physical features of binoculars which strike you first, are basic design, central focusing knob/wheel and diopter.

Basically binoculars would come with two basic designs

1. porro prisms

2. roof prisms

The ones using porro prisms are the traditional design where the eye pieces are off-center to the barrels, whereas the ones using roof prisms the eye pieces are in line with the objective lenses and have a sleek design. Porro prism binoculars are less expensive and have greater three-dimensional viewing effect, whereas roof prism binoculars are more compact and lighter, but are usually more expensive.

The optics of the Binocular are made  with premium optical glass and are coated with our own natural color transmission multi-coating which boosts light transmission much higher than similar binoculars in this price range and yields extraordinary clarity, resolution and color fidelity.

It has a  unique “Fast-Focus” system which turns from close focus to infinite distance in two full turns of the focus wheel, for razor sharp fine tuning. The focusing is smooth and precise, and it’s waterproof.
Since birds are skittish by the presence of bright or light colors, Steiner tried the opposite approach with the exterior finish of the Merlin: the almost transparent neutral color on the Merlin is a unique earth tone brown; chosen by Steiner’s development staff and birders as a color least noticeable to birds.

To hold the binoculars properly it’s better to buy a lighter binocular. Easier to hold better the view.

Exit Pupil:

This is the size of the image at the focusing point of the binocular. It is computed by dividing the objective size by the magnification. The exit pupil of an 8×40 binocular is 5mm (40/8). A larger exit pupil means a brighter image. Binoculars over 3mm are considered good for daytime birding and anything over 7mm is a waste.

Eye relief:

Eye relief is the distance from the rear eyepiece lens to where the image is formed. Eyeglass wearers should look for binoculars with at least 15mm of eye-relief and have eye-cups that can be folded down. This will allow them to enjoy bird-watching.

Close Focus:

Good birding binoculars should have a close focus of 10 feet or less otherwise you may find yourself walking backwards to try and see something. How close a binocular focuses depends on how it is made rather than on its power.

Body Design:

There are two basic types. i) Porro prism Binoculars and, ii) Roof prism binoculars. Roof prisms are lighter, rugged, easier to maintain and usually waterproof. Porro prism binoculars are cheaper, Optical quality is not markedly different though roof prisms being more expensive usually have better coating.

Binoculars are what makes bird-watching pleasurable – so invest in the best that you can afford, they are sure to give you years of memorable moments.

Binoculars are most often used by people who travel. Binoculars are mainly helpful in journey travel, such as traveling to national parks or safaris, where the explorer might want to view wildlife. Travel binoculars are usually lighter and more solid than usual binoculars. They effortlessly fit in a carry on bag, and some are tiny enough to fit in a pouch.

Machinery of Travel Binoculars

It’s always good to know the working of binocular before you choose.

Prism

With the help of prism you see the images right-side-up when looking through the binoculars. Travel binoculars usually have roof prisms, which are present inside the optical tube of the binoculars. It reduces the space and makes it great to travel.

Lens Coating

Glass surfaces are coated that touch the outside air. The coating helps transmit the light. Its better to look for binoculars which are fully coated. Multicoated binoculars reduces glare.

Magnification and Objective Lenses

Magnification is the power of the binoculars. Magnification is usually confirmed 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 lesser 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.
