Far Infrared (FIR)
What is the source of the warmth that we fill? How do human beings generate heat?
The answer is – Thermal Infrared Radiation
The unseen radiation that is one of the enabling parameter that there are life on earth.
From innovative technological solutions to cutting-edge space exploration, thermal infrared plays a crucial role in most industrial and scientific sectors.
This article delves into the fascinating world of thermal Infrared, exploring its origins, properties, and impact on our lives.
The Electromagnetic Radiation
Electromagnetic radiation in divided into a wide range of waves and in many times is considered as the electromagnetic spectrum. These wave travel through space and matter as a function of their energy. The electromagnetic spectrum is classified by wavelength and frequency; the shorter the wave, the more energy it carries. Short wave length (low frequency) like gamma or x ray are very energetic, whereas longer wave length (high frequency) such as micro or radio waves are less energetic. Most of the electromagnetic radiation we as human cannot fill it with our senses, expect from the visible that we can see with our eyes, and thermal ranges of the spectrum we can sense heat.
The visible range of the spectrum is a small portion from the whole spectrum between 0.4 to 0.7 micron, whereas, the thermal radiation ranges on a wide range from 4 – 15 micron.
Where can we meet thermal radiation?
Thermal infrared radiation was discovered centuries ago, and since then, it has remained one of the most influential forces in science. In every object that we know on earth, also very cold one like our freezer at home, their peak energy is in the thermal range of the spectrum. For instance, the maximal radiation from a freezer that is (-4) Co is at 10.5 micron, and boiling water is at 7.5 micron.
Because thermal radiation spans on a wide range of wavelength , Acktar specialty is blackest black coatings that perform extremely low reflectance over a range wide of the electromagnetic spectrum extending from the visible to the thermal range with one product, Fractal Black. The coatings are designed for stray light absorption and reflection minimization increasing thermal cameras sensitivity (SNR) or in other words decreases the NEDT (Noise Equivalent Delta Temperature).
Thermal cameras are used in many application such as military, security and search & rescue.
So, will TIR keep shaping the future innovations in health and technology in general? Only time can tell, until then, we will keep developing and coating the needed instruments to optimize their performance.
