Infrared Forehead Thermometer
An infrared thermometer is a thermometer that infers temperature from a portion of the thermal radiation sometimes called black-body radiation emitted by the object being measured.
An infrared thermometer is a device that measures the infrared radiation – a type of electromagnetic radiation – a type of electromagnetic radiation below the visible spectrum of light- emitted by an object. The most basic design of infrared thermometers consists of a lens to focus the infrared thermal radiation onto a detector, which converts the radiant energy into an electric signal. This configuration facilitates temperature measurement from a distance, without the need for contact with the object to be measured.
