Question

What is Infrared thermometer and how it works ​

Answer 1

IR light works like visible light—it can be focused, reflected or absorbed. Handheld IR thermometers typically use a lens to focus light from one object onto a detector, called a thermopile. The thermopile absorbs the IR radiation and turns it into heat. The more IR energy, the hotter the thermopile gets.

Answer 2

Infrared thermometers usually use a lens to focus infrared light from one object onto a detector called a thermopile. The thermopile absorbs the infrared radiation and turns it into heat. ... The electricity is sent to a detector, which uses it to determine the temperature of whatever the thermometer is pointed at
