The peak wavelength refers to the wavelength at which the radiation energy is maximized in a black body.
The peak wavelength refers to the wavelength at which the radiative energy of a black body is maximized. It is sometimes mistakenly assumed that the peak wavelength of a black body can be determined using Wien's law to match the maximum absorption wavelength of the material being processed, and that the temperature of the far-infrared heater can be set accordingly. However, this is incorrect; calculations should be based on Planck's law. At any temperature, the amount of radiative energy on the short wavelength side of the peak wavelength is only 25% of the total radiative energy, while 75% is in the long wavelength range. [Trivia: Peak Wavelength and Radiative Energy Distribution] - For far-infrared heaters, up to 1000°K, there is more energy in the far-infrared range. → For a far-infrared heater with a surface temperature of 800°K (527°C), the radiative energy above 3μm accounts for over 80% of the total radiative energy. - By using a far-infrared heater and determining the heater temperature that can heat the material to the desired temperature, efficient heating can be achieved.

basic information
【Trivia: Peak Wavelength and Radiation Energy Distribution】 ○ The peak wavelength is the wavelength at which the radiation energy is maximized in a black body. ○ When determining the temperature of a far-infrared heater, it should be considered and calculated using Planck's law. ○ At any temperature, the amount of radiation energy on the short wavelength side of the peak wavelength is only 25% of the total radiation energy, while 75% is in the long wavelength range. ○ For far-infrared heaters, up to 1000°K, the far-infrared range is more prevalent. → For a far-infrared heater with a surface temperature of 800°K (527°C), the radiation energy above 3μm accounts for more than 80% of the total radiation energy. ○ By using a far-infrared heater and determining the heater temperature that can heat the material to the desired temperature, efficient heating can be achieved. ● For more details, please contact us or download the catalog.
