Furthermore, the shell 1 is made of titanium alloy, stainless steel or plastic.
Because the optical fiber light source generator is used in the fields of hairdressing and beauty, optical medical treatment or optical hairdressing and beauty, the optical fiber light source generator is contacted with more chemical hairdressing agents and water, and the shell 1 made of titanium alloy, stainless steel or plastics can ensure the safety and stability and is not easy to corrode and pollute. In addition, the density of titanium alloy, stainless steel or plastic is low, so that the optical fiber light source generator is reduced in weight, and people can not feel fatigue due to hand fatigue even if holding the optical fiber light source generator for a long time.
Furthermore, the light-collecting column 3 is made of plastic.
Because the density of the plastic is very low, the weight of the light collecting column 3 is further reduced, and the optical fiber light source generator is convenient for people to hold.
