What is the range of night vision binoculars?
7x Night vision binoculars have a range of 50 meters to infinity.
What is an Image Intensifier Tube: Gen 2+ “Level 2”?
The Gen 2+ “Level 2” Image Intensifier Tube (IIT) is a component used in night vision devices. It works by amplifying ambient light, allowing you to see in darkness. The key difference between the night vision generations is the intensifier technology. Gen 2 devices have added a micro-channel plate that multiplies the number of electrons before they make contact on the phosphorus screen, thus increasing clarity, quality, and brightness.
SPI Corp offers Gen 2+ image intensifier tubes (IIT) in five levels: B1, B2, B3, W1, and W2. All Gen 2+ night vision tubes are equipped with a microchannel plate and multi-alkaline photocathode, with the primary differences between the levels being resolution and cosmetic quality.
The Gen 2+ IIT NL1, also known as “Level 1”, represents the highest quality Gen 2 IIT offered by SPI Corp. It boasts a resolution of 55-72 lp/mm, which is indicative of its superior image clarity and detail.
In terms of field of view cleanness by zone, the Gen 2+ “Level 1” is virtually spotless in Zone 1, meaning there are almost no visible imperfections or “spots” in the image when viewing objects in this zone.
This high level of image quality makes it ideal for applications that require clear and detailed night vision.
In summary, the Gen 2+ “Level 1” offers the highest resolution and cleanest field of view among SPI Corp’s Gen 2+ offerings, making it a top choice for demanding night vision applications.

What does a Field of View (FOV) of 5.4 Degrees mean for 7x night vision binoculars?
To calculate angular to linear FOV is easy. Multiply the angle by 52.5 to get the linear feet FOV. For example, if a binocular says it has an FOV of 7 degrees, it means you can see 5.4 degrees x 52.5 = 293.5 feet of a scene from left to right when looking at 1000 yards. This is because one angle degree is equal to 52.5 feet.
The rule is simple. Increase magnification, decrease field of view. When you crank up the power on your binoculars, you’re going to see less of an area as you get more specific detail on your target or scene. When you dial back down to low magnification, the field of view will become wider as you see more of the surroundings in your view.
In practical terms, a narrower FOV like 5.4 degrees might mean you see less of the overall scene at once, but what you do see will be magnified more (since these are 7x binoculars) and in greater detail. This could be beneficial in situations where you’re trying to observe specific details in the dark, such as wildlife or distant objects.
What is the highest magnification in binoculars?
The highest magnification in binoculars is typically around 20x to 25x, but extremely high magnifications may compromise stability and image quality.
What is a Long Range Infrared Illuminator?
A long-range infrared illuminator is a device that emits infrared light, which is invisible to the human eye but can be detected by night vision devices. This technology is often used to enhance the performance of night vision devices in low-light conditions, effectively increasing their range and detail. All of our night vision products, including our 7x night vision binoculars, come with a long range infrared illuminator.
Here are some benefits and uses of long-range infrared illuminators:
What is the significance of a 192 mm; F/2.13 lens in regards to night vision binoculars?
Light Gathering: The objective lens (the first lens in the system) is responsible for capturing the dim visible light reflected from the subject, along with some light from the infrared spectrum. The size and aperture of the lens (in this case, 192mm; F/2.13) can affect how much light it can gather, which is crucial for the performance of night vision devices
