Infrared ray .

In light spectrum，wave length from 0.75 to 1000 um is called infrared light ，also call infrared ray. The infrared belong to the field of electromagnetic wave and just like ir led strip。The infrared ray. Possessing special electromagnetic wave function 。 the application of infrared can be seen everywhere. Such as: Through the absorption of infrared ray. and reflection of visible light, fluorescent brightening agents ( FBA) can enhance the whiteness and brightness of fabrics.
the range of infrared ray’s very wide .the infrared ray was divided by different wavelength. They divide them into three type：

*Near infrared ray: It is most commonly used for Breast disease; General investigation. Such as Near infrared ray scan.

*Middle infrared：This is wavelength are high temperature sensitive. it can be applied to new developments in detect temperature technology.

*Far infrared: also known as live light. it have a positive effect on the human . it can boost the subcutaneous temperature， Effectively improve the physique, cleanse the blood and the activate cells. Bring in that health change , can cleanse your blood and other substances which is harmful. 。beneficial to human health and other substances which is harmful.
