STSZ Laser — Precision Laser Module Manufacturer Since 2018

   Founded in 2018, Shenzhen STSZ Laser Technology Co., Ltd. designs, manufactures, and supplies precision laser solutions for industrial alignment, measurement, and positioning applications. Our 3,000㎡ production facility in Xinghe Industrial Park, Chaoyang District, Shantou, Guangdong houses complete in-house manufacturing — from optical component assembly and precision collimation to final quality control.

   Our product range covers 16mm and 22mm diode modules, 520nm green line generators, and fully custom optical configurations. We primarily serve clients across Southeast Asia and emerging markets, working with wholesalers, distributors, OEM integrators, and research institutions.

   Backed by a 10-person engineering team and roughly 100 production staff, we handle optical design, driver circuit development, and mechanical structure in-house — enabling full customization from wavelength and power output to beam shape, divergence angle, and housing geometry. Custom prototypes ship in as fast as 10 days, standard units within 1-3 working days, and we accept small-batch orders with flexible MOQs.

   Quality is built into every stage: ISO 9001-certified processes, CE-compliant design, and 2 design patents plus 1 utility model patent protect our structural innovations. Each unit passes wavelength verification, power calibration, beam divergence testing, 24-hour burn-in, and laser safety classification before leaving the factory — ensuring consistent output, long operating life, and reliable field performance.
