Wide Field

Binoculars are important for different types of people. The military people need them to have a check on what is going on in the opponents' camps. On the other hand, there are the birdwatchers and wildlife lovers who need the binoculars to watch different animals and birds without disturbing their natural way of living. Also, there are several other uses of the binoculars. However, regardless of the purpose of using the binocular, it is important that the binocular is a powerful and precise device. Otherwise, you will not be able to observe things as perfectly as you want to.

Now, the quality of the good binocular depends on the contrast, sharpness and the intensity of light. All these are dependant on the lenses and prisms of the binocular. This is why most of the professionals prefer the Olympus binoculars. For, they are the leading brad in the manufacturing of the binoculars in the world and their fame comes mostly because of the quality of their lens and prism.

One of the very important factors that decide the optical precision of the binocular is the field of view or what is also called as the angle of view. Basically, this tells you how wide an area you will be able to see with the help of a particular binocular. Generally, this is measured in degrees. Also, the field of view can be expressed in metres when a person views an area from 1000 metres. Now, if you are going to observe wildlife, sports, or any moving object, it is important that your binocular has a wide field of view. In this regard, the Olympus binoculars have brands like 7x35 DPS I with which you can view 162 metres from the distance of 1000 metres.

Another very important factor for good binocular is of course the lens. Ideally, this lens should aspherical. If made properly, the aspherical lenses will prevent all the distortion and at the same time, will ensure plasticity, bright pictures, and sharp contours. Now, you will be happy to learn that the Olympus binoculars have the aspherical lenses in most of their products.

Finally, there is the question of the prisms. In the high performance binoculars, the prisms are coated in such a way as to preserve the image detail and the brightness. Basically, they are a special type of optical glass that refracts the minimum amount of light and thus retain the clarity of the image. There are basically two different types of prisms available - the porro prism and roof prism. The former presents three dimensional images and occupies greater space, while the later offers reduce the image to present compact image.

However, if you are looking for the Olympus binoculars and pentax binoculars, the Microglobe is the best place to purchase it. They have experts who will help you in making the right choice. At the same time, they will offer the best price in the market. What's more, they will deliver the product at the earliest so that you don't have to wait long to receive your Olympus binoculars.
