980nm is a common wavelength for infrared lasers. Infrared light with a wavelength of 980nm has the following characteristics.

Compared with other wavelengths of infrared rays, 980nm wavelength has a window in the absorption spectrum of infrared rays in the human body, which means that the human body's absorption of infrared rays of 980nm is relatively low, and the permeability is relatively high. Therefore, 980nm laser is used in the field of medical cosmetology, such as laser hair removal, skin cosmetology, etc., can be more deeply absorbed, the effect is better.

980nm wavelength of infrared light is easy to be detected by silicon-based photodetectors. Many industrial infrared distance sensors, infrared obstacle avoidance sensors choose 980nm as the working wavelength.

980nm laser beam is more concentrated, higher energy density, so used in laser cutting, laser welding and laser marking and other industrial processes. For example, laser cutting machines, laser marking machines are widely used 980nm wavelength infrared laser.

980nm wavelength infrared by many infrared emitting tubes and light-emitting diodes can effectively transmit and receive. Therefore, they are used in infrared communication, infrared alarm systems and night vision devices.

The production technology of 980nm infrared laser is relatively mature and inexpensive, which also promotes the wide application of 980nm infrared in various fields.

Therefore, 980nm infrared has a high transmittance, easy to detect and relatively low cost advantages, which makes it has a very wide range of industrial and medical applications, is the infrared in the most frequent use of one of the bands.
