01
Source, not trader
Blanks are processed, polished, coated and inspected here. Export customers talk to the same engineers who hold the interferograms.
江苏天核初芯科技有限公司
Jiangsu THOI Technology Co., Ltd.
A source factory in Changzhou, Jiangsu — the Yangtze River Delta — with R&D, custom and mass production of infrared optics. Twenty-plus years in the trade, specialized in zinc selenide.
02
ZnSe as a craft
CVD zinc selenide is unforgiving. We stayed with it — then added ZnS, silicon, chalcogenide and metal OAPs without leaving the IR.
03
Qualified shop
ISO quality certification on the wall, Zygo plots in the packet, witness coupons for every coating run.
