Infrared radiation

Infrared radiation is a form of electromagnetic radiation with longer wavelengths than visible light but shorter than microwaves. It lies between visible light and microwave radiation in the electromagnetic spectrum.

Infrared radiation is not visible to the human eye because its wavelengths are outside the range it is capable of perceiving. Its spectrum is divided into three main categories:

Near Infrared (NIR): This is closest to visible light in the infrared spectrum. Wavelengths range from about 0.75 micrometers to 1.5 micrometers.

Mid Infrared (MIR): This part of the infrared spectrum has wavelengths from about 1.5 micrometers to 5 micrometers.

Far Infrared (FIR): This is the farthest part of the infrared spectrum with wavelengths from about 5 micrometers to 100 micrometers.

Infrared radiation is important to many fields, including physics, engineering, medicine, and thermography. Its use is found in many applications such as thermal imaging, remote control, security systems, therapeutic and diagnostic devices in medicine and more. Infrared radiation is also used in industry for heat detection, temperature controls, drying, heating and many other applications.


Infrared radiation is important in heating, because it can directly heat objects and the human body, without the need to heat the air in the room. Compared to traditional heating systems that heat the air, infrared heating offers several advantages:

Targeted heating: Infrared radiation is able to directly heat objects and surfaces in a room, including walls, furniture and the human body. This minimizes heat loss in the room and ensures targeted and efficient heating.

Even distribution of heat: Infrared heating provides an even distribution of heat in the room, as the heat spreads directly from the heating source to the surfaces. This minimizes thermal unevenness and creates a comfortable environment.

Fast Responses: Infrared heating systems have a fast response time, which means they heat up quickly and start producing heat when turned on. This enables the desired temperature in the room to be reached more quickly.

Energy savings: Infrared heating can offer energy savings compared to other heating systems. Heat is generated directly on target surfaces, which minimizes heat loss and increases energy efficiency.

Health Benefits: Infrared radiation can have several positive effects on the human body, including improving blood circulation, relaxing muscles, and promoting overall well-being.

Infrared heating is often used in a variety of applications, including home heating systems, commercial spaces, patios, bathrooms, wellness centers, and more. It is a modern and efficient heating method that provides a comfortable and energy-saving environment.
