In 2023,Do you often travel or explore at night? Do you want to see more in the dark? If so, you may need night binoculars. Night vision binoculars is an amazing device that allows you to see clear images in the dark, just like an owl. However, there are some basic knowledge and considerations you should know before buying night time binoculars. In this article, we will introduce you to the concept, principle, classification, performance, usage, and maintenance of infrared binoculars for hunting to help you choose the right night binoculars.
What is binoculars with night vision?
First, let’s understand what binoculars with night vision is. Night vision binoculars is a device that allows you to observe a target in a dark environment, and it utilizes shimmering light enhancement or infrared imaging technology to magnify or convert faint light into a visible image. binoculars with night vision optics are available in a variety of types and uses, such as military, hunting, and wildlife observation. The price and performance of infrared binoculars also vary greatly; generally speaking, the more advanced the night vision device, the more expensive it is, but also the clearer and more stable it is.
However, not all binoculars have night vision. Some people mistakenly think that as long as a layer of red film plated binoculars is night binoculars, in fact, this kind of binoculars does not have any night vision role, just slightly increase the light only. Some people want to buy the kind of American blockbuster night-vision glasses, in fact, this kind of glasses in the market is not for sale, both at home and abroad. Even if there is, it is estimated that the price is very expensive. Some people think binoculars have night vision, in fact, binoculars cannot night vision. Unless it is a night vision device with night vision optics function, the observation distance is usually not very far. Some people confuse night vision devices with binoculars, but they are actually different devices. True night vision devices can not be used during the day, and the imaging is not clear color, usually yellow-green or black and white.
So, how to distinguish real binoculars with night vision? We can judge from the following aspects:
- APPEARANCE: True night binoculars are usually a bit larger than normal binoculars and have a special switch or button to control the night vision function.
- Marking: True infrared binoculars are usually marked on the casing with their model number, generation, manufacturer, etc. and have a special logo to indicate that they have night vision capabilities.
- EFFECTIVE: True night time binoculars provide clear and stable images in the dark with adjustable magnification and brightness. While ordinary binoculars can’t see anything in the dark or can only see blurred and flickering images.
How do night binoculars work?
Next, let’s learn how night binoculars work. The principle of infrared binoculars is to utilize a microlight intensifier or thermal imager to amplify weak light so as to display a clear image on the screen. A microlight intensifier is a device that converts visible or near-infrared light into an electronic signal and enhances the brightness and contrast of the signal through amplification, filtering, and processing. It allows you to see in moonlight or starlight as if it were daytime. A thermal imager is a device that converts far-infrared light into an electronic signal and displays the temperature distribution of an object through color coding, temperature calibration, and image fusion. It allows you to see in complete darkness, just like with thermal vision. How do night binoculars work? We can briefly describe it in the following steps:
- Use one eye (objective lens) to catch very little bright light, which may come from visible or infrared light reflected or emitted by the target object.
- You can make a bright light even brighter or change its color with a tiny device (like a microlight intensifier or a thermal imager) that turns the light it catches into a signal and makes the signal stronger and clearer by boosting, sorting, and working on it.
- You can show a bright light on a screen (eyepiece) that changes signals into light and shines it into your eyes. Then you can see a sharp picture on the screen.
What types of night binoculars are available?
Next, let’s see what kinds of night vision binoculars there are. It can be grouped into different generations and types based on how
they work and how well they work. Based on how they work, night vision optics can be grouped like this:
- Shimmer Enhanced: These night time binoculars use a shimmer booster to make visible or near-infrared light bigger, and need some light around, like from the moon or stars. They usually have a bright yellow-green picture and can be changed for size and brightness. They are good for using in places where the moon and stars are few or city lights are bright.
- Infrared imaging type: These infrared binoculars use a thermal imager to change far-infrared light, don’t need any light around, and can work in total darkness. They usually have a color or black and white picture and can show how hot or cold something is. They are good for using in places without moon or stars or in the dark of the countryside.
- Laser-enhanced: These night-vision binoculars use a laser sender to send out an invisible ray of infrared laser light, and then a microlight booster or thermal imager to catch and make bigger the bounced back picture of the laser. They can work in any light, but need something that bounces back the laser. They usually have a clear and bright picture and can change how strong and where the laser goes. They are good for using in special jobs or urgent situations.
Depending on their performance, night vision optics can be categorized into the following generations:
- Generation 1: These are the earliest and most basic infrared binoculars, use simple microlight intensifiers, require more ambient light sources, have poorer image quality, more noise and distortion, lower magnification, and shorter battery life. They are usually cheaper and suitable for recreational or leisure use.
- Second Generation: These are the more usual and everywhere night vision optics that use better microlight boosters, need less light around, have better picture quality, have less noise and mess, bigger size, and longer battery life. They are usually more costly and good for expert or army use.
- Generation III: These are the best and most amazing night vision optics that use the newest microlight boosters, need almost no light around, have very good picture quality, almost no noise or mess, very big size and very long battery life. They are usually very costly and only some countries or places can get them.
- Generation IV: These are night-vision binoculars that are still being made, using more better technology and stuff to give the sharpest and most steady pictures in all light, with more things and things they can do. They are expected to be very costly and to be used by very few countries or places.
What is the scope of night vision binoculars?
Finally, let’s know the range of infrared binoculars. Night binoculars have a big range of uses and are used in the following places:
- POLICE: night binoculars also have an important part in police work, and can be used for night watching, chasing, looking for and other jobs, which makes law work better and fairer.
- WILD WATCHING: Night binoculars also have an important part in wild watching, which can be used to see wild animals, plants, stars and other natural things, which makes watching better and fun.
- DRIVING: it also help a lot on driving trips, and can be used for getting the way, lighting up, and emergency stuff in the dark, making travel safer and easier.
- CAMPING: it also help a lot in camping and can be used for setting up tents, getting fire, defense and other stuff in the dark, making camping cozier and safer.
- ROCK CLIMBING: Night binoculars also help a lot in rock climbing, and can be used to pick ways, holds, protection and other stuff in the dark, making climbing better and safe.
- EXPLORING: it also have an important part in exploring, and can be used to explore unknown places in the dark, find new things, avoid danger and other things, which makes exploring more exciting and rewarding.
- In conclusion, Night binoculars is a very useful and interesting device that allows you to see more in the dark and adds more color to your life. If you want to buy quality infrared binoculars, you need to consider the following aspects:
- Generations of night vision devices: the higher the generation, the better the performance, but also the higher the price. Generation I night vision devices are the most basic and suitable for recreational use; Generation II and III are military grade and suitable for professional use; Generation IV is the most advanced, but also the most expensive.
- Magnification of the night vision device: the higher the magnification, the farther the observation distance, but also the more difficult to stabilize. Generally speaking, 2-5 times is a more appropriate range.
- Objective lens caliber of night vision device: the larger the objective lens caliber, the more light intake, the clearer the image, but also the heavier. Generally speaking, 40-60mm is a more appropriate range.
- Battery life for night vision: the longer the battery life, the longer you can use it. Generally, it should last at least 4 hours.
- Versatility: Some night vision devices can be used in conjunction with other equipment, such as cameras, video recorders, laser sights, and so on. These features can add to the enjoyment and effectiveness of use.
