The heat sensing scope is actually a camera that takes images of infrared light that cannot be seen by the human eye and translates it into visible light.

These have an uncooled detector at room temperature, allowing the user to see the basic image output needed within the temperature range from -4f to 4000f.

Optical Facility

It provides three variety of lens options as 25mm, 50mm, and 75mm to get better visual and clear detection.
