Coolest Uses of Infrared Technology

Pain Relief

Infrared Radiation has long been used as a method of pain relief and treating skin diseases. The infrared rays act as deep penetrating light energy passing through the skin and producing heat from within. It's seen as safe and gentle. So much so, in fact, that many hospitals use it to keep newborns warm. In short, infrared can be harnessed to help pain, stiffness, cramps, and tension.

Night Vision

The principal that all objects emit an infrared energy as a function of their temperature is the science behind how night vision works. The hotter an object is, the more radiation it will emit. Thermal imaging is the process that collects the infrared radiation from objects in a scene and turns it into an electronic image for viewing at night.

TV Remotes

A typical tv remote uses infrared energy just beyond the visible spectrum of light-infrared light waves to change the channels on your television. This light is so faint however that you cannot see it with the "naked" eye. They typically only have a range of about 30 feet and require a line-of-sight. This means it won't work around corners or through other objects.

Infrared Lamps

Heat lamps transmit infrared radiation to a body or object. Infrared heat lamps are usually incandescent bulbs which are able to produce infrared radiation by heating a filament wire to a high temperature. The useful part of the energy is visible light, but most of the energy is given off as heat in the near-infrared wavelengths. Common industrial applications include cooking and heating food, heating reptile tanks, drying paint, and printing ink.

Home Heating

Infrared heaters produce heat as a product of invisible light. The warmth that's generated is the same as that from the sun or a sidewalk. This is essentially warming objects from within. You can feel the warmth radiating into your skin. Most infrared space heaters have 3 parts that help create the heat: infrared light bulbs, a heat exchanger, and a fan that blows air onto the exchanger to disperse the heat. View our Infrared Technology page for more insight on how this technology works.

Meteorology

Satellites use infrared sensors called radiometers to produce infrared images of the Earth's atmosphere. This allows trained analysts to determine cloud height, calculate water and surface temperatures, and locate ocean surface features.
