Infrared refers to the wavelength range from 0.7 μm to 500 μm (Infrared light), Which can be subdivided into near infrared, mid infrared, far infrared three regions.Near Infrared: refers to the
wavelength range from 0.7 μm to 2.5 μm (infrared light).middle Infrared:refers to the wavelength range from 2.5 μm m to 25 μm (infrared light), middle ir light is analysis of molecular structure
of the most useful, the most information rich region ---- Far infrared: refers to the wavelength range from 25 μm to 500 μm (infrared light). Ultraviolet spectrum wavelength between 100nm to
400 nm, in generally divided into three categories:UV-A (315 nm-400 nm, also known as UVA) ,UV-B (280 nm- 315 nm, also known as UVB),UV-C (100 nm -280 nm, also known as for short
wave ultraviolet).UV LED early uses of Dental treatment instrument and forgeries. UV LED current use include: optical sensors and instruments (230nm-400nm),UV authentication, Barcode
(230nm-280nm), surface water sterilization (240nm-280nm) identification and analysis of body fluids (250nm -405nm), Protein analysis and drug invention (270nm -300nm), medical lights
therapy (300nm-320nm), polymers and inks (300nm -365nm), forgeries (375 nm - 395nm), surface sterilization / Beauty sterilization (390 nm-410nm).
