    How Do Night Vision Binoculars Work?

    Night vision was once something referred to only in James Bond movies and the offices of private detectives, but now everyone can take advantage of the benefits of night vision binoculars. But just how do they work? Read on to find out more.
    In layman’s terms, any night vision device or technology works by amplifying all available light to provide an image. Even when our eyes feel like an area is pitch black, there is still light present on the lower portion of the infrared light spectrum which our eyes cannot see. Much equipment now also has a built-in Infrared illuminator which provides additional light for when there is none or little to take advantage of.
    As light is collected by the objective lens, it is sent to an image intensifier photocathode tube, which usually runs off battery power. This converts the photons from the light energy into electrons, which then pass through the tube and cause atoms in the tube to release similar electrons, meaning that there are thousands more than there were originally. These thousands of electrons hit a screen coated with phosphors at the end of the tube, which then generates the release of photons and create the green image that we associate with night vision.
    This green image is seen through another lens, known as the ocular lens, which then allows for some magnification and focus. However, unlike bird watching binoculars, for example, night vision binoculars are not designed for magnifying remote objects, and usually have a very low degree of magnification. Consequently, the larger the object you want to view, the easier it will be to see, and details depend on how much natural ambient light you already have. The purpose of night vision binoculars should simply be to see in the dark, rather than to see great distances or great details as you would with a regular pair of binoculars.
    All night vision devices are classed by their ‘generation’. The generation refers to the type of image intensifier tube which is used, and which ultimately is responsible for creating the image. 1st generation devices are the most popular and provide bright, sharp images at a low cost. 2nd generation devices are commonly found in professional applications, such as in use by the police or armed forces, and the subsequently cost a significant amount more. Meanwhile, 3rd generation devices are the ultimate in night vision technology and use gallium arsenide to give a sharper and brighter image. Again, these devices are significantly more expensive than a 1st generation device.
    Here at Sherwoods Photographic, we are specialists in digital night vision equipment and have an extensive range of night vision goggles, monoculars, binoculars and gun sights available. Whatever you want to use your night vision device for, whether it be for hunting at night or for observing nocturnal wildlife, we have something to meet your needs. We’re always happy to help if you have any questions too, so don’t hesitate to get in touch.

    Gifts for the Outdoors Type

    Anyone who loves the great outdoors should be pretty easy to buy for, right? Well, whilst it may seem that way, getting them something that they don’t already have can be hard work. After all, those who spend a great deal of time outdoors, will understand just how important it is to be prepared for everything from hiking trips to lengthy time spent camping out.

    Whilst you may well be able to do a little bit of digging and find out exactly what they might be lacking or needing, there are plenty of items that even the most experienced outdoorsman might not have considered purchasing but that will almost certainly improve any outdoors experience for them.

    Certain items of very technical clothing can be a very good present, but making sure you get something that is a perfect fit will be extremely important and therefore potentially a big task. Instead, consider items that might improve what they can achieve. For example, even those with the very best binoculars for bird watching, or hiking equipment, may not have considered night vision equipment.

    Whilst night vision goggles or cameras may well be associated with spies and intrigue, in reality they can be the perfect tool for those who love the outdoors. Not only are they a great way to be able to optimise binoculars when wishing to view wildlife in its natural habitat, but they can also help people to get around more safely, to be quieter and in turn not wake others when they need to get around at night and even potentially just be safer from potential threats, should they find themselves in the middle of nowhere in the dark.

    So when it comes to gifts for the outdoors type, think outside the box and consider which items might really improve what they can achieve.

    Think you don’t need night vision? Think again.

    There’s more to night vision than meets the eye. It offers far more usable benefits that you might think with it being much more than a way to hunt, spy or survey, because if you’re interested in wildlife observation it can bring the twilight hours to life in a way you never thought possible.

    There’s nothing better than being able to observe the great outdoors, and your garden could easily be a hub of wildlife activity. If that’s the case then chances are it’ll be just as active at night, if not more so—it’s in the hours of darkness that the truly interesting animals come out to play, and you could well find that your garden is home to far more than a few birds and a frog or two. Basic binoculars will hold you back from all that and if you keep any lights on you’ll frighten any visitors away, so the only thing to do is invest in night vision.

    But, don’t think you’ll have to invest in outrageously expensive or overly large pieces of equipment, because thanks to rapid technological advancements in the area you might be surprised at the options open to you. Monoculars, goggles, scopes and even binoculars are all available with this specialist feature, and you won’t have to spend a fortune to get products of the necessary quality. You could easily be missing out on a wealth of wildlife observation opportunities by not having this piece of technology in your life, and if you want to see the types of products on offer just get in touch and we’ll gladly fill you in.

    Spotting Endangered Species

    Are you a nature lover who would love to spot some endangered species? Perhaps you dream of seeing a Great Bittern in flight, or maybe you want to spot a Harbour Porpoise while visiting the ocean?

    If you want to spot endangered animals and enjoy seeing them in nature, you will need to learn as much about them as you can. Where do they live and what do they eat? Do they come out during the day, or are they only nocturnal?

    Once you know enough about the species that you want to see, you can then begin to plan an excursion. You will need to think about acquiring the appropriate gear, such as hiking boots or waterproofs. And if you will be in the mountains, you may need thermals, and if you will be on the water you may need lifejackets.

    You will also want certain equipment such as binoculars. These are vital in your search for endangered species as you may never come close enough to one of these animals to actually enjoy it if you don’t use binoculars.

    Depending on when the animal you want to see comes out, you may also need night vision binoculars. These are great for watching animals that come out at dawn or twilight as you may need to be in place while it is still dark.

    Here at Sherwood we sell a great range of binoculars that are ideal for watching wildlife. Please see our main web site for more information about our products.

    A new world of possibilities with night vision devices

    Technology is developing all the time and this has had a huge impact on the world of vision. These days, it’s possible for ordinary consumers to purchase great value telescopes and other such products to enable them to pursue their hobbies.

    Among the most impressive offerings available for individuals to buy are night vision devices. These come in a range of different styles, but they all have one thing in common: they allow people to see in conditions that would normally be too dark for human eyes to work.

    One common use of these items is wildlife observation. Many animals behave completely differently at night time, so using specially designed pieces of equipment to see them can open up an whole new world.

    Meanwhile, for those intent on something more active, it is possible to use night vision gun sights and monoculars to get stuck into some hunting in the darkness.

    If you think you could benefit from such devices, you have come to the right place. Here at Sherwoods we stock an extensive and varied range of night vision items, meaning we should have the perfect ones for you, regardless of your objectives.

    And, if you know someone else who would love to receive such offerings, or telescopes and so on, you may want to purchase the products as a festive gift.

    To see whether any of our devices take your fancy, just have a look around the rest of our website. You might be surprised by the level of choice you face.

    Does Night Vision Actually Work?

    When many people ponder about night vision goggles, the images of spy films usually come to mind.  With many things in spy films being completely hocus pocus, many people also believe that night vision is one of these myths.  But really, they actually work!  With the proper equipment, you really can see people up to 200 yards away on a cloudy dark night.  Night vision technology generally follows concepts of two trends.  These two trends are thermal imaging, and image enhancement.

    Thermal Imaging simply works by capturing the upper portion on an infrared spectrum.  What this means is that heat is omitted and turned into light when viewing into the night vision goggle.  Therefore, you can see where heat is, and where heat is not.  This makes our warm human bodies stand out from cold trees.  Thermal imaging is great for nocturnal animal lovers.  This technology allows the viewer to see nocturnal animals in their natural habitat, which when considering the dark nights, is a rarity.

    Image enhancement works in a very different way that thermal imagery.  It basically works by collecting tiny fragments of light and digitally enhancing and amplifying them.  Light is captured into an image enhancing telescope with the traditional objective lens.  However, as with a normal telescope where the light would travel untreated, an image enhancing telescope intensifies the light with electrical power.  Simply put, light that normally would not be perceived by our naked human eye is amplified, allowing us to see in extremely low-light situations.
