ABOUT US

Founded in 2016, the company is engaged in the R&D and manufacturing of laser patterning component-level products.

Co-founded by a National Distinguished Expert under the Ten-Thousand Talents Program for entrepreneurship, the company has a technical team of over 50 professionals with 11 years of experience in optomechatronics R&D. It owns more than 120 intellectual property rights in laser speckle reduction, light source integration and shaping, high-precision exposure lens design and assembly, as well as DLP/CMOS chip development.Our products are widely used in laser direct writing, semiconductor-like lithography, additive manufacturing, machine vision, laser cinema, biomedicine and other fields.

Headquartered in Science and Technology City, Suzhou National High-tech Industrial Development Zone, Jiangsu Province, the company has two wholly-owned subsidiaries:Beijing ZT Vision Tech Co., LTD. located in Beijing Yizhuang Economic Development Area,and Shenzhen Really High-Tech Co., Ltd. located in Longhua District, Shenzhen.

With the mission of "Providing key components for laser applications and creating social value together with customers", the company continues to conduct R&D on laser patterning applications and contributes to the development of the industry.

What is laser patterning?
Using a laser as the illumination source, the light is modulated by DLP or LCoS and then projected onto the exposure surface.
Line laser or area laser is used as the illumination source to irradiate the surface of the measured object. After passing through the lens, the light is imaged onto a CMOS device, thereby obtaining 2D or 3D image information.
Design capabilities including semiconductor laser spatial coupling / fiber coupling, laser speckle suppression, illumination optics, imaging optics, as well as high-precision assembly and alignment capability for imaging lenses.
