A thermal scope works by detecting the heat that’s radiated by an object such as an animal, a person, or any non-living object. With the modern advancements in technology, thermal scopes are now more available in the market than before.

They are highly versatile and suitable for multiple applications such as hunting, home surveillance, and law enforcement among others.

When shopping for a thermal scope, you’ll want to know how far you can shoot with it. With thermal scopes, the detection range varies from one scope to the other. A scope can help you identify a target that’s far away, but you must first recognize what it is before you can make the shot.

The detection and recognition distance varies greatly depending on the weather condition and the size and posture of the target. To help you get a better understanding of how far you can shoot with a thermal scope, let’s take a look at some of the important factors that affect a thermal scope’s detection and recognition range.

Factors that Affect a Thermal Scope’s Detection Range

Objective Lens

The larger the objective lens, the better. It will give you a wide field of view that’s needed for easy target identification. A larger objective lens also provides a stronger ability to receive infrared radiation for high-quality image views. It’s also much simpler to recognize a target that’s far away with a large objective lens without losing its imagery quality.

Thermal Detector

The larger the thermal detector, the more temperature radiations it will absorb. The result is clear and more detailed images that make it easier for you to distinguish what target it is. When all the other factors of the unit stay unchanged, a scope with a large thermal detector will help you shoot more accurately regardless of how far the target is or how big or small it is.

The algorithm, OLED, and Eyepiece

After the thermal energy is projected on the FPA, the FPGA will convert it into digital signals after which the display will show the image. The algorithm, resolution, and size of the OLED display have a direct effect on the magnification of the image. Lastly, the image will be magnified further by the eyepiece before it reaches your eye.

Since thermal scopes can be used during the day and at night as well, they will help you detect distant objects that are hiding in the bushes or camouflaged. Moreover, how far you can positively identify the target will largely depend on the quality of the scope.

With a top-tier thermal scope, you can spot a target that’s up to 4,000 yards away while an entry-level unit can limit you to less than 1,000 yards. For you to shoot a target that’s this far accurately, you must have a positive identification of what it is, its size, and know what posture it has at that particular time.
