What is the principle of thermal imaging night vision device?

You have asked the core of this question, understanding the principle can better understand its advantages! The core principle of thermal imaging night vision devices is to detect the infrared radiation (heat) emitted by the object itself, rather than relying on visible light, and ultimately convert invisible thermal signals into visible images.

In which scenarios are thermal imaging night vision devices suitable for use?

​The core advantage of thermal imaging night vision devices is that they do not rely on visible light and can detect the heat of objects for imaging. They are suitable for scenes with extremely dark light, obstruction, or the need for concealed observation, and are mainly used in the following four fields.

How to choose a suitable thermal imaging sight for oneself?

Thermal Sensitivity (NETD): Thermal sensitivity reflects the ability of a device to detect small temperature changes. The smaller the value, the higher the thermal sensitivity, the smaller the temperature difference that can be detected, and the stronger the level of imaging. However, there may also be more false targets. Generally speaking, thermal sensitivity of 20-50mK is more commonly used.

What is the typical field of view for binoculars?

The field of view of binoculars is usually expressed in degrees or linear distance (meters/1000 meters), and its value may vary depending on factors such as the telescope's magnification, objective aperture, and eyepiece design. Generally speaking, the actual field of view of binoculars is around 3 ° to 8 °, corresponding to a linear field of view range of approximately 50 meters to 150 meters at 1000 meters.
