5 things you didn’t know about binoculars


When it comes to binoculars, people think they know everything about these ingenious devices. But they still have secrets that wait to be discovered by a curious mind. To facilitate that, I’ve put together a list with some of the coolest facts that remain unknown to the general public.

Binoculars use efficient eyepieces which include potent lenses, to bring distant objects closer. They can have many other features besides that, like night and thermal vision. The devices were invented a long time ago, and they serve different purposes. Binoculars are mostly used in military missions and by hunters and adventurers.

But what people sometimes forget, is that binoculars can act as telescopes. They work pretty much on the same principle, although a high-quality telescope can offer considerably more detail when looking at the night’s sky. On the other hand, binoculars are much more comfortable to use, as they can be handheld.

Using binoculars to stargaze is something that can bring you a lot of satisfaction, especially if you want to observe the fascinating details of the Moon’s surface. If you are an amateur astronomer, with the help of binoculars you can also spot comets, supernovas and many other celestial bodies that might be of interest to you.

Another cool thing about binoculars is that you can use them with a lightweight monopod, which can be cheaper than a heavy tripod. Or, if you are crafty, you can even use a traditional tripod to secure your device. Most people use this combination when they want to keep the binoculars in the same position, especially when looking at stars from a roof or a tree house.

Did you know you can use binoculars as a microscope? If you reverse the object and if you look through the large lenses at anything from the size of an ant up, you can see the rich detail of the microcosmos. Granted, it’s not going to be as efficient as a traditional microscope, but it will still be fun to discover what the world we cannot see with the naked eye has to offer.

The great scientist Ignazio Porro invented the modern binoculars, invention which he called prism binoculars. He used a prism erecting system, which offered more detailed and a stable image, even in low-light conditions. Even to this day, this patent is often used in the manufacturing of binoculars, along with the roof prism design, which allows the product to be more compact.

Another thing that people don’t know about binoculars is that you can use them to take pictures of distant objects or views. The zoom on your camera is often inefficient, so using a high-quality pair, like the binoculars from Vortex, along with a DSLR camera, can solve that problem in an instant.
