Night Goggles Military - Of course, fans of action movies are already familiar with military thermal goggles, but not everyone knows that such a device exists in real life. In addition, it is widely used by the military (obviously) and is successfully used commercially. So what exactly is this device and how can we benefit from using it in our daily lives?
Military thermal goggles are a special device that allows the user to see in total darkness thanks to special optical and infrared radiation. The entire device consists of a video intensifier tube, which is well protected from damage and water by a special housing.

As for the principle of operation, the user does not see a real photo, but a reproduction of the image, when he measures the heat from the target only by infrared rays. Therefore, it does not need any ambient light to function not only during the day but also at night. Specifically, IR radiation measures the wavelength and renders an image based on the result. The image is mostly monochromatic: the higher the target temperature, the brighter the image. However, the latest versions of military thermal imaging devices can produce a multi-color image.

It is a reliable device that can work for 24 hours without stopping, and the resistance is at a high level. However, this type of equipment is better suited for tactical purposes, such as detecting and identifying a target, rather than hunting it. So it will just be a nice addition to the weapon.
In fact, such a vital device could not even exist without the discovery of infrared radiation. Fortunately, in 1800 astronomer Sir William Herschel made the necessary discovery. Since then, infrared light has been mainly used to measure temperature. As a result, everyday life has been actively working with new technologies, which has created a great need to produce suitable detectors and sensors for bolometers and thermometers. And Leopoldo Nobili took another game-changing step: applying the Seebeck effect, in 1829 he brought the world's first thermocouple. It was the best version of a regular thermometer and a crude version of a thermopile. The development of detectors was interrupted by the First World War. However, since 1913 there have been more and more new discoveries for civilians where IR technology has been successfully applied.
The first military thermal camera appeared in Great Britain for air defense in 1929. The inventor was Kálmán Tihanyi, a physicist from Hungary. Meanwhile, in the US, he scanned the line. This device was developed by a joint venture between the commercial company Texas Instruments and the US military in 1947, but it had a major drawback - it took an hour to draw an image.
In the 1950s, advanced alternatives were adopted for British defence. It was a linear scanning device consisting of a special detector and a continuously rotating mirror that was triggered by the slightest movements of any flying object. It was called the Yellow Duck, which was the prototype for the first application of fixed-line optics to protect against underwater attacks. Unfortunately, the expected function of the wake-up detection system did not work well, but it was the impetus for the active application of IR scanning technology for military purposes.

Since then, there have been several more important discoveries, but the last one that made military thermal vision production grow so much was pyroelectronic optics and solid-state thermal imaging arrays. They were the basis of all modern thermal vision devices, which are controlled by a single crystal cut hybrid.
Currently, all thermal imaging devices are divided into two types: with cooled or uncooled detectors. Both have specific characteristics that may be appropriate for certain conditions. Let's take a closer look at each of them.
Devices with uncooled detectors are often found in units because they are cheaper due to the simplified manufacturing process. First of all, these gadgets have sensors that work at ambient temperature. The working principle is to measure the heating value of the current, resistance and voltage after the infrared beam directed at the object by the infrared beam. It then automatically compares the output with the input values to render the image. These designs do not guarantee high accuracy results, especially low image resolution.
Equipment with cooled detectors is an expensive option due to its manufacturing technology and additional equipment that supports its proper operation. The point is that the detector is cooled by a tightly closed vacuum vessel, which must be cooled continuously. Such a solution allows the devices to work at extreme temperatures and obtain the highest image accuracy. Military thermal goggles are part of this type of thermal vision device to ensure high quality results for users.

The dimensions of thermal equipment (including military) are almost unlimited. In addition, the technology is still being developed, so it is rightly considered a vital product of mankind, especially for defensive purposes. However, it is also important to use thermal imaging devices. In particular, the construction industry and heat leakage, humidity in the home, etc.
It should be noted separately that IR technology is also actively used in medicine and veterinary medicine. And, of course, these devices are pioneers in astronomy and space discoveries.
In addition, some principles are successfully applied to household appliances and devices that we use every day. So, it's safe to say that thermal imaging equipment can solve almost any problem you may encounter. So if you can't find the exact instrument, it doesn't mean it doesn't exist. In fact, similar devices can be customized to your needs or even made new to suit you. However, to do this, it is better to consult professionals such as Ms.. Night vision goggles are different from night or trip; blind through it. We've partnered with Night Vision Devices, one of the largest manufacturers in the United States, to bring you everything you need for the night.
All night vision products and accessories are controlled by International Trade in Arms (ITAR) export laws and regulations. By purchasing equipment from Night Vision Devices, you understand that these products may not be exported without a valid license from the US Department of State.
U.s. Army Tests New Enhanced Night Vision Goggle Binoculars
The NVD-BNVD-SG White Phosphor Night Vision Binoculars are dual-tube binoculars with gain control. The BNVD-SG can be used as a monocular by choosing which side you want to use as a night vision eye and flip the other side/binocular up and out of the way. This enhanced capability allows the user to rotate any monocular channel away from the eyes while leaving the other monocular channel in place. This gives you the flexibility to use the BNVD-SG as a binocular or monocular device. When used as a monocular, the user can operate the BNVD-SG with weapon sight equipment without losing night situational awareness.
The BNVD-SG now features a "Tactical Monocular Cutoff" that cuts off power to each binocular channel when the channel rotates outside the user's line of sight. This eliminates the light coming from the monocular eyepiece that would expose the wearer to anything else on the battlefield. The BNVD-SG has an automatic power off system every time the BNVD-SG turns up in the helmet storage position and then turns back on when it comes down again. This feature can also be disabled with the four position ON/OFF switch. The BNVD-SG is available with an optional battery pack that includes 3 AA alkaline batteries for over 50 hours of operation.
With our extensive capabilities and strategic partnerships, we can build any of our NVD products with video amplifiers from Elbit Systems of America®, Photonis® or L3Harris®. These include green and white phosphors and thin or filmless picture tubes. This system complies with MIL-STD 810G, MIL-PRF-A3256342A(CR) and MIL-PREF-49427(CR).
