infrapunalämpötilamittauksella

Infrapunalämpö, often referred to as infrared radiation, is a type of electromagnetic radiation that lies just beyond the visible spectrum of light. It is a form of energy that can be felt as heat. All objects with a temperature above absolute zero emit infrared radiation. The hotter an object is, the more infrared radiation it emits.

Infrared radiation is invisible to the human eye, but we can perceive it as warmth when it strikes our skin. This is because our skin's nerve endings are sensitive to the energy transfer from infrared photons. The wavelengths of infrared radiation range from approximately 700 nanometers to 1 millimeter. This range is further divided into near-infrared, mid-infrared, and far-infrared, each with slightly different properties and applications.

One of the most common applications of infrared heat is in heating systems. Infrared heaters work by emitting infrared radiation that directly heats objects and people in their path, rather than heating the air itself. This can be more energy-efficient in certain situations compared to conventional convection heating. Infrared technology is also used in various other fields, including thermal imaging cameras for night vision and medical diagnostics, remote controls, and industrial processes like drying and curing. The ability to detect and utilize infrared radiation has opened up numerous possibilities for technology and everyday life.
