Binoculars, or binocular telescopes, have achieved what very few other gadgets can boast; longevity. There have been evident progressions in the technology of a binocular telescope and various types of this product have been produced. However, the core principle and method of functioning has never altered. This is a gadget that is as useful now as it was 20 years ago – how many other technologies can you say this of? This article explores the world of the binocular further; enlightening you to how they function as well as other pieces of crucial and interesting information.

What pieces make up the puzzle?

Before you can understand how binocular telescopes work you first need to be aware of what they are made of, in other words; the key parts of the gadget. There are three essential components that make up the functioning of binoculars. Binocular telescopes have two crucial lenses. There is the larger lens – most commonly known as the objective lens. And then there is the smaller lens – people refer to this as the prism. The latter plays a crucial role as it bends the light. If it wasn’t for a prism then anyone looking through a pair of binoculars would see the image upside down. Furthermore, the final significant part of the binocular is the eyepiece. This component is what makes the image visible to your eye.

Step by step – How do binocular telescopes work?

You are now aware of the three components found in a pair of binocular telescopes; the objective lens, the prism, and the eyepiece. Let’s discover how they function together to give our eyes the vision we see when we look through a pair of binoculars. The objective lens is placed at the front of the gadget. It captures the light, which then moves through the lens and starts travelling through the prisms (remember; these are the smaller lenses). The prism corrects the orientation of the image. And the final movement of the light takes place from the prism to the eyepiece. The eyepiece concludes the procedure via magnifying the image so that it is visible to the human eye.

What makes a quality image?

When you go to buy a pair of binocular telescopes you will be met with a lot of different types of this product on the internet. However, you may be wondering why some are priced higher than others and alike. After all, they all use the same procedure mentioned in the previous paragraph. Nonetheless, the reason for this is because there are various components that actually determine the level of quality regarding the image you see. First and foremost, you have the quality of the glass used in the lenses. This is pivotal in creating sharp, accurate, and colourful images. The more expensive binocular telescopes will use dense glass that has been perfected through various sophisticated techniques. In addition to this, you must consider how big the exit pupil is. This is the light that leaves the eyepiece and consequently enters your eye. The bigger it is the better the image will be. And last but not least, all lenses have anti reflection coatings. This is crucial in lowering the light scatterings and creating sharper images. Therefore the quality of the coating also determines the quality of what you see when you look through the eyepiece of your gadget.

Hopefully you now have a better understanding of how a binocular telescope works. It is fascinating to see how three key pieces operate in order to create groundbreaking results.
