Three-dimensional woven preform Optical Material Feilihua
Thickness [2.5D thick flat plate product series]: 1~90 mm Width [2.5D thick flat plate product series]: 100~1300 mm Honeycomb cell edge length [Honeycomb structure series]: Customizable
3D woven preforms are anisotropic and readily support near-net-shape weaving of complex structures with high design flexibility. Warp and weft contents are tailored to directional mechanical requirements. Fabric rigidity can be adjusted for subsequent manufacturing and service conditions of different composites. These 3D preforms can be customized to customer requirements.

Three-dimensional braided preform Optical Material Feilihua
Thickness [Three-dimensional woven plate series]: 1~40 mm Width [Three-dimensional woven plate series]: 10~200 mm Length [Three-dimensional woven plate series]: 5 m
3D integral braiding produces variable or irregular cross sections. Changing carrier-array shape, yarn fineness on each carrier, and carrier motion directly forms 3D preforms to a part's shape and dimensions, preserving overall structural performance. The 3D products are formed integrally in one operation, with a nonlayered structure, greater interlayer strength, and improved overall mechanical properties.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
For low-frequency RF, electromagnetic testing and power combining systems, conventional resistive power dividers bring high insertion loss, while standard directional couplers cannot provide equal-amplitude signals with 180° phase shift. They fail differential circuits, balanced amplifiers and signal cancellation systems.
