On May 5, 2020, SZLB Optoelectronic Technology Corporation, a leading optical technology manufacturer in China, developed a large aperture liquid crystal polarization grating using unique patented technology.
Liquid crystal micro nano technology is a method of utilizing self-developed lithography technology to regulate the arrangement of polymer molecules at the submicron scale, which can prepare different high-precision phase structures on thin films of several micrometers and achieve specific beam modulation functions.
Based on our own capability reserves in core materials, core lithography equipment, and fully automated mass production processes, superior and stable hardware and production conditions, as well as a group of highly educated professional and technical talents.
SZLB became the first enterprise in China to independently manufacture micro/nano optical devices based on birefringent liquid crystal polymer materials.
SZLB has become a global leader in the research and application of liquid crystal micro nano technology, with broad prospects in aerospace, LiDAR, laser processing, laser lighting, medical aesthetics, and other fields.
Other products of SZLB:
The phase of the incident laser is modulated by controlling the arrangement of the polymer liquid crystal molecules, that is, the azimuth of the fast axis of the liquid crystal molecules and the thickness of the liquid crystal layer. The orderly arrangement or specific pattern arrangement of the polymer molecules is achieved through the optical orientation technology to reshape the incident laser beam, such as intensity distribution (hollow ring, uniform light, Gaussian flat top), spot shape (round square, polygon), Phase distribution (vortex light), polarization state (linear polarization – circular polarization, reverse rotation) and other information.
