Infrared radiation refers to electromagnetic radiation. The wavelength of infrared radiation is longer compared to that of the light which is visible. But the wavelength of infrared radiation is shorter if compared to that of the microwaves. The wavelengths of infrared radiation range between 750 nm and 1 mm. Infrared implies below red. The color red possesses the longest wavelength. Infrared light can be experienced as soon as the rays of sun fall on the skin.
There are a considerable number of uses of Infrared imaging. It is widely used for military purposes. Apart from this infrared imaging is also needed for civilian purposes.

It is used for the acquisition of target, tracking, and surveillance. Besides this infrared imaging is used for the purpose of analyzing thermal efficiency. It also helps in spectroscopy, sensing of remote temperature, and also in the forecasting of weather. Infrared light can also be felt if in case you experience the warmth of fire. Generally common people believe light only as radiant energy that can be seen by naked eyes. But the light which can be seen by naked eyes is only a small part of all the different kinds of light that have existence. Infrared light is a particular kind of light. This particular kind of light known as infrared can never be seen by naked eyes.
Apart from infrared light , there are different other category of light as well . These lights include Gamma rays, ultraviolet light, radio waves, X-ray, and microwaves. All these light cannot be seen by naked eyes. All the aforementioned rays constitute the same kind of electromagnetic energy. When something is seen by the help of the light that is visible , the eyes can distinctly differentiate between the the light of the various waves. The light of the various waves seem to the eye as different colors. The light which is longest appear to be red in color. The light with the shortest wavelength is blue. True that the waves of the light cannot be seen , but the color is clearly visible. It is terms of the color that the different things and aspects of the world are interpreted.
The wavelength of each and every color can be distinguished from each other without any difficulty. The light of violet color is visible at the wavelengths of about 0.4 micron. Again the light of yellow color have wavelength of 0.6 microns. The red color light possesses wavelengths of 0.65 microns. Light possessing Your eyes cannot see light that has a wavelength more than 0.7 microns can never be seen by naked eyes. The infrared light refers to that particular light having the wavelength ranging between from 0.7 micron and 0.1 millimeter. The strand of infrared light is wider if compared to that of the light which we can see. Not only the infrared films but also the common video cameras are extremely sensitive to what is called the infrared light. For more information on Infrared, browse through our site infraredxl.com.
