ABOUT US

___


Photonicsland Technology Co., Ltd. was founded in early 2014. It is a national high-tech enterprise, specialized in production and sales of various types of fiber fiber grating and special optical fiber. 

At present, the company is equipped with three important production equipment: Excimer writing system (fifteen systems), Femtosecond laser writing system and fiber drawing tower online writing system. We can produce common sensing fiber gratingslong period fiber gratings, fiber gratings for fiber laser, 1650nm (or 1625nm) reflection filter fiber gratings for communication, extremely high temperature fiber gratings...
