How Does The Objective Lens Diameter Affect The Image
The diameter of an objective lens impacts the amount of light thats allowed in and transmitted to your eye. While theres a tendency to think bigger is always better, the other design elements of a specific pair of night vision goggles also play a role in image quality. When it comes to choosing night vision goggles, its important to know that a larger lens diameter means more opportunity for your goggles to capture ambient light. But factors such as glass quality, magnification, and IR illumination will also dictate image quality.

Types Of Night Vision Goggles
There are two different types of night vision goggles available on the market today. They are IR night vision goggles and Thermal night vision goggles.
Infrared Night Vision Goggles
Modern night vision goggles use IR illumination. They dont depend on the ambient light present to create an image. Instead, they use IR rays to provide you with the target images. These IR waves come from anything that emits heat.
IR night vision goggles come in handy when you are viewing targets in total darkness. Youll have a clear view of different targets at any range while you remain hidden.
Thermal Night Vision Goggles
Thermal night vision goggles work the same way as IR night vision goggles. However, they detect the actual heat that an object releases. These goggles provide clear target views at any time of the day. Since they depend on heat signatures to create an image, you can use them at night and in broad daylight as well.
Night Vision Goggles Vs Night Vision Binoculars
The term “goggles” in night-vision, is somewhat of a catch-all term that includes bioculars, binoculars, and monoculars. When mounted to head or helmet gear for hands-free use, it’s now used as goggles. This is why you’ll see binoculars and goggles used interchangeably in the industry. However, bioculars have a single tube design easily distinguished from binoculars with their two eyepieces and single objective lens body.
The AN/PVS-7 is a night vision biocular, and all PVS-7 models from various manufacturers design their NV goggles after this military issued night vision single tube device. It is by far the most popular NV type of goggles available, and consequently, it’s one of the cheaper models.
As you know, binoculars, with night-vision or without, often come with much higher magnification. For hands-free operation and moving in the dark, you need 1x power for the utmost stealth and natural vision.
As mentioned earlier, 1x power, smaller apertures, and included head gear are the iconic features of what separates goggles from ordinary monoculars and binoculars.

How Does Night Vision Work
To put it as simply as possible, night vision goggles gather what little light is available into the objective lens. This light enters a photocathode tube thats filled with gallium arsenide. Inside the tube, the light energy is converted into electrical energy . These electrons then pass through a microchannel detection plate that essentially amplifies that electrical energy. This increased energy then passes through a phosphor screen that converts the electrons back into photons, or visible light. This visible light is what you see when you look through the eyepiece and the amplification typically produces a bright greenish hue that we usually associate with night vision.
The Top Considerations When Buying Night Vision Goggles
It should be as simple as finding some that are of quality, have a look thats appealing to your personal aesthetic, and fit within your budget. These may be important considerations, but they are far from the only ones youll need to ponder before purchasing military night vision goggles. Take a closer look at some of the things you dont want to overlook before you buy:
The right thermal night vision goggle will get you the results you desire, but the wrong choice is simply a waste of effort and money. But now that you know what to consider, get to know how night vision goggles work and the best options available on the market.

Types Of Night Vision Generations Explained
Night Vision Generations dictate price, clarity, brightness, and longevity. You will typically see them labeled as GEN 1-4. The US military after analyzing GEN 4 technology decided that it was still just slightly improved GEN 3. Therefore you will still see some companies marketing GEN 4, or 3+, but for simplicity, we will stick with the US military and use 1-3.
Generation 1 night vision has been around since the 1960s and used in the Vietnam war. At the time it was certainly better than nothing, but as you can see from the photo above, as the generations progressed, so did the clarity, and price as well. Another thing worth nothing is there are different degrees of quality for each generation. The US military gets first picks on the best tubes coming off the production line. This is why you will sometimes see quality differences between two of the exact same generation tubes, and even models.

Nightfox Swift Best Under $200
In general, night vision goggles under $100 and $200 will be very similar. With digital technology and limited range, the distinctive differences between the two price lines will be its helmet-mounting compatibility. The NightFox Swift includes a head mount and 1x magnification suited to goggle use.
The NightFox Swift is a 1x zoom digital goggle set. Its designed with a single display and an eyecup that surrounds both eyes. Included with the Swift model is a simple head mounting strap that allows for hands-free use. For complete hands-free operation for mobility, a more secure and quality head or helmet mounting system would be required.
As an NVD, it can be used safely in color mode during the day and then it switches to black/white mode for night vision. It is a small display with low resolution, but it suffices for recreational CQB use and varmint hunting.
Its detection range is between 10-70 yards. Though the NightFox Swift has adjustable IR illuminator settings, the emitter lights glow red compromising detection and your position. Both the manufacturer and buyers report the best options for improving stealth and increasing range to 100 yards is to turn off the IR illuminators on the Swift and use an external IR flashlight. That will be a separate purchase but perhaps fitting for nerf, airsoft, or hunting applications.
