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.
Anyone that’s looked out into their garden at night could well be surprised by what they see. It’s an entirely different landscape complete with different wildlife, and with the right conditions you could experience a whole new world in your very own back garden. The only problem with that is it can often be difficult to see what’s out there – put on any lights and you’ll instantly scare away any nocturnal animals that could be about – which is why night vision could be the perfect solution.
This technology has come into its own in recent years, and new developments combined with a reduction in price means that everyone can now reap the benefits. There are small devices or binoculars that are perfect for home use – they can simply be kept in the conservatory for when the mood arises or for when you can spot something particularly intriguing – or you can go for more advanced options if you want to keep a closer eye on things. Whatever you choose you’ll find a wealth of wildlife-spotting opportunities when the twilight hours hit, and if you’ve got binoculars ready and waiting you won’t have to miss a thing.
We know that there’s nothing better than seeing your garden come alive at night, which is why we’ve got an extensive selection of night vision devices to ensure there’s something for everyone. We can even advise on the best products for your particular needs and budget and we’re confident you’ll find something to suit, so get in touch today and you’ll soon be seeing your garden in a whole new light.
As a supplier of first rate astronomical telescopes and optics, there’s nothing we love more than all the invaluable odds, ends and gadgets on offer to enhance your celestial viewing, camping or bird watching experiences.
You’ll understand the logic that each of us here in the Sherwoods studio has our own optical viewing hobbies. We’re made up of astronomers, outdoor pursuits fanatics, twitchers and nature lovers; but the one thing we all agree is a must is night vision capability. We stock lots of different night vision optics and accessories to suit a huge range of interests and budgets, e.g. lightweight, long-distance etc. A red light torch is also a must for localised light-sensitive viewing such as referencing space charts or field guides.
A really great field guide is invaluable in all areas of interest. Most folks (us included) prefer to keep things compact and concise, so our range of star maps, bird watching guides etc. are all noted for their ease of use, portability and long-term relevance.
Once you’ve spent a long evening with your eye plastered to an astronomical telescope, you’ll understand why soft eyecups are invaluable! Most of our eyecups are designed for both day and night viewing, with some featuring great light pollution reduction design elements.
The best of astronomical telescopes won’t help you read a space chart on a blustery UK night! A simple compact magnifying glass is considered basic kit by bird watchers and astronomers alike.
Always on the lookout for great opportunities to try out the latest in astronomical telescopes, we’re all looking forward to the 2011 calendar of celestial events across the UK!
Organised annually by Loughton Astronomical Society and Kelling Heath site management, the 2011 Autumn Equinox Sky Camp – held on Kelling Heath, Norfolk – looks set to be one of the brightest and biggest group astronomical viewing events in the 2011 UK calendar. The main event runs over the weekend of 24th-25th Septemer 2011, with extending camp options covering the 19th-30th September 2011.
Astronomical telescopes aside, the party is a great place for hundreds of like-minded astronomers of all abilities to get together and trade celestial tips and astronomically useful star gazing guidance. Children are welcome, as are groups.
The evening/night of 24th September is considered the main event, but there are plenty of lectures and discussion groups to get everyone through daylight hours too! Non-camping entry is free, but those wishing to drive home should be aware that car movement is stringently restricted once darkness falls.
Special Sky Party camping areas are set aside at a reduced rate for groups or individuals wishing to stay the night (or a few!) Lighting regulations are strict, so, as past Sky Camp attendees, we’d have to say that night vision optics can be invaluable for everything from finding dropped keys to adjusting the sight of your telescope!
If the Sky Party sounds like your cup of celestial tea, we’ll see you there with our night vision gadgets and top of the range telescopes!
For those folks who just can’t resist the urge to throw on a backpack and explore the great outdoors, lightweight kit is essential. You need devices and equipment that both perform and don’t weigh you down!
We offer a brilliant range of compact binoculars designed specifically with portability and easy use in mind. The leading brands we carry on our roster – Nikon, Olympus etc – all offer great models that excel in use, durability and portability. Our recommendation of the day is Nikon’s Sprint IV 8×21 binoculars; perfectly designed for easy usability and extreme adventure!
Some folks struggle to find a practical use for night vision optical devices, but when you’re looking for a lost hiker or trying to spot something on the dark slopes of Snowdon, you need high performance, lightweight night vision optics that deliver high quality images. Lightweight (620g) single lens models like the Cobra Nemesis offer high performance at low cost via hardy design (rubber armouring) and cutting edge technology.
The Celestron Astromaster range features several lightweight and compact telescope designs (between 8.16-10.69g) ideal for the intrepid stargazer. The entire Astromaster series is designed for multi-purpose celestial and land viewing, making the budget price models in the collection a good investment for those looking to a) meet their adventurous viewing needs, and b) not spend so much on a device that they’re too worried to use it out in the mud and wind of Mother Nature!
Night vision is normally associated with police and spies in films. However, night vision has many practical applications. Basically, night vision refers to a device that allows an image to be to be seen in situations where it would be otherwise too dark to see it. Night vision can be achieved either via binoculars or goggles, and you may be surprised by how useful they can be.
Night vision devices work by gathering ambient light that is normally not visible to the naked eye. This can be infrared light, moonlight or starlight. The light is then transferred to a part of the ‘Image Intensifier Tube’ (IIT). Usually, light is made up of protons, but when it enters the IIT, it is transformed in electrons. These electrons are then combined with a phosphorus screen which changes the electrons into light that can be seen by the human eye. The user of the night vision goggles or binoculars then sees a green tinted image of the scene in front of them.
Although the police regularly use night vision, it has many other regular uses too. Night vision can aid a variety of hobbies, including fishing and bird watching. It can enable them to enjoy their hobbies at times when they wouldn’t otherwise have been able to. Night vision is also great for campers. When you are camping, there are often situations where you need to move around at night. While a torch can help with this, night vision makes it as simple as moving around during the day.
Some animals have adapted to see in the dark but humans are not among them. Our eyes are adept at picking up on visual stimuli in natural or artificial light, but in the absence of such illumination, we struggle to view our environment.
However, thanks to our immense powers of imagination and scientific prowess, we have been able to devise instruments that enable us to watch things in the dark. There are now many night vision products available for people to purchase. Indeed, you can get such offerings from us here at Sherwoods. We stock a number of these creations, along with our telescopes and other provisions.
Over the last few years, night vision optics have come a long way. Whereas in the past, such technology was the preserve of a privileged few, such as certain armed forces personnel, these items are new accessible to ordinary consumers.
For example, wildlife enthusiasts and researchers can watch animals using the devices.
Also, the offerings can come in useful for those keen to spot game, hunt and keep track of creatures. Indeed, many of the offerings are small and light, meaning they can fit into their users’ pockets and rucksacks easily.
If you are keen to get such devices and want them to last for as long as possible, you might also want to think about choosing versions that are water resistant.
