What is the range of our best gen 3 night vision binoculars with long range infrared illuminator?

If you are using binoculars with 7x zoom to view an object that is 10 miles away, it will appear as if it is only 1.43 miles away. The 7x magnification makes the object appear approximately 1/7th of its actual distance, effectively reducing the apparent distance. So, an object 10 miles away would look much closer, appearing as if it is 1.43 miles away when viewed through the 7x zoom binoculars.

What is an Image Intensifier Tube: Gen 3+ “Level 1”?

Our best gen 3 night vision binoculars, Gen 3 IIT 3NL1, are a high-resolution night vision device, renowned for its exceptional image quality. Offered by SPI, it is considered the cleanest and highest resolution device in their range. This device is characterized by having practically no visible spots in Zone 1, indicating a clear and unobstructed field of view.

What does a Field of View (FOV) of 7 Degrees mean for 10x night vision binoculars with long range infrared illuminator?

A Field of View (FOV) of 5.4 degrees means that when using the 7x night vision binoculars with a long-range infrared illuminator, you can see a horizontal span of approximately 5.4 degrees from one edge to the other when looking through the binoculars.

Mathematically, you can calculate the width of the FOV using trigonometry. The formula to find the width of the FOV in feet (assuming you are using binoculars) is:

Width of FOV (in feet) = 2 * (Distance to the target * tan(FOV/2))

For example, if you are observing an object that is 1000 feet away and the FOV is 5.4 degrees:
Width of FOV = 2 * (1000 * tan(5.4/2)) Width of FOV ≈ 2 * (1000 * tan(2.7)) Width of FOV ≈ 2 * (1000 * 0.0472) Width of FOV ≈ 2 * 47.2 Width of FOV ≈ 94.4 feet

So, at a distance of 1000 feet, the binoculars with a FOV of 5.4 degrees will allow you to see a horizontal span of approximately 94.4 feet.

What is the highest magnification in binoculars with long range infrared illuminator?

The highest magnification in binoculars with long range infrared illuminator 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 best gen 3 night vision binoculars, come with a long range infrared illuminator.

Here are some benefits and uses of long-range infrared illuminators:

Enhanced Night Vision: Infrared illuminators can significantly improve the performance of our best Gen 3 night vision binoculars, allowing for better visibility in low-light or complete darkness. This can be particularly useful for activities such as hunting, wildlife observation, or surveillance.

Undetectable Illumination: Since infrared light is invisible to the human eye, an infrared illuminator can provide light without alerting people or animals to its presence. This can be useful in surveillance or hunting scenarios.

Long Range: As the name suggests, long-range infrared illuminators can provide illumination over a greater distance than standard infrared illuminators. This can be beneficial in situations where the user needs to observe or target something from a distance.

Versatility: Infrared illuminators can be used in a variety of settings, including military operations, law enforcement, hunting, wildlife observation, and even paranormal investigations.

Safety and Security: Infrared illuminators can be used in security cameras to provide clear images even in complete darkness, enhancing the safety and security of properties.

Astronomy and Astrophysics: Binoculars with long range infrared illuminators are also used in the field of astronomy and astrophysics to study celestial bodies that emit infrared radiation
