Infrared Thermometer

INFRARED THERMOMETER: On its most basic design an infrared thermometer consists of a lens to focus the infrared (IR) energy on to a detector, which converts the energy to an electrical signal that can be displayed in units of temperature after being compensated for ambient temperature variation.
The IR thermometer is that it focuses infrared light at an object to detect and measure energy or radiation coming from its surface. The detector then translates the amount of electricity generated into a temperature reading.
Research has shown that, when used correctly, infrared or no-contact thermometers are just as accurate as oral or rectal thermometers. No-contact thermometers are popular among pediatricians, as kids often squirm around when trying to get a temperature read, but it also holds true in mass temperature screenings.
Infrared thermometers offer a unique advantage over other tools: they have the ability to measure temperatures from a distance, without the need for direct contact. This feature makes them invaluable in various areas.
When the infrared radiation falls on the thermopile surface, it gets absorbed and converts into heat. Voltage output is produced in proportion to the incident infrared energy. The detector uses this output to determine the temperature, which gets displayed on the screen.
