Brief introduction
Infrared radiation is in fact a kind of electromagnetic wave radiation . Different frequencies make up a very wide spectrum---from visible light to infrared ray. Temperature of the heater (filament or carbon fiber) decides the distributing of the heater radiation intension according to the wave length. According to the location of the maximum radiation intension in the spectrum distributing, Infrared heating tubes are classified to: short wave (wave length: from 0.76 to 2.0um), middle wave (wave length: from 2.0 to 4.0um) and long wave (wave length: above 4.0um).
