[Discussion on Far Infrared] Differences between Near Infrared and Far Infrared

Introducing the differences between near-infrared and far-infrared!

In Japan, wavelengths of 3μ or more are referred to as far infrared, while those below are called near infrared. We have devised a far infrared heating system suitable for Japan that can be processed with compact equipment, which is expected to yield efficient and high-quality results. Furthermore, continuous production is now possible, leading to labor savings. The radiation energy of near infrared heaters is constant, and the wavelength distribution follows Planck's radiation law. The heating element is a metal filament sealed within a glass tube filled with inert gas. While the temperature of the heating element cannot be measured directly, the maximum radiation wavelength from a 2000°C filament is approximately 1.3μ. Thus, heaters with a maximum wavelength of less than 2 microns are referred to as near infrared heaters, and since the maximum radiation wavelength from a 1000°C filament is about 2.3μ, heaters with a maximum wavelength of 2 to 4μ are classified as mid-infrared. *For more details, please refer to the PDF document or feel free to contact us.*
