What is Infrared
Energy?
The electromagnetic spectrum is divided into three segments by wavelength,
which is measured in microns (1/1,000,000 of a meter).
0.76 to 1.5 microns
= near infrared = 0.000029921259842519687 Inches to 0.00005905511811023622
Inches
1.5 to 5.6 microns
= middle infrared = 0.00005905511811023622 Inches to 0.00022047244094488188
Inches
5.6 to 1000 microns
= far infrared = 0.00022047244094488188 Inches to 1000 Microns = 0.03937007874015748
Inches

This wavelength of
light warms objects without warming the air between the source and the
object (known as conversion).
This radiant heat can also be called Infrared Energy (IR). Do not confuse
this with UV radiation (sunburn) or atomic radiation (nuclear) - see the
diagram above for where these types of light fall on the spectrum. Infrared
waves are not visible to human eyes but can be seen by special instruments
that translate infrared into colors that are visible to our eyes. The
best example is the sun (80% of the suns rays are infrared). Our
atmosphere allows infrared rays in the 7 to 14 micron range to safely
reach the earths surface.
When warmed, the earth radiates infrared rays with its peak output at
10 microns.
The human body radiates infrared energy out through the skin at 3 to50
microns, with most around 9.4 microns.
