Pure Germanium Stone Application

Contains trace elements that are beneficial to the human body, such as selenium, zinc, nickel, etc., and the initiator wave emitted by these elements is the same wave state as the initiator wave of human cells, which can promote blood circulation, enhance metabolism, and help improve immunity.
High transparency in the infrared band and can generate and detect infrared light, so it is widely used in infrared optoelectronics fields such as infrared sensors and infrared focal plane array cameras
