Features
Fused Silica Hexagonal Microlens Arrays Key Features
- We use advanced photolithography technology combined with precision etching to achieve micro-nano structure fabrication.
- Fused silica is used as the substrate, offering high temperature resistance, corrosion resistance, and excellent transmission from UV to near-infrared with minimal absorption and scattering.
- We adopt hexagonal microlens units, which provide higher optical energy utilization and more uniform light spot distribution compared to traditional circular lens units due to their high fill factor.
- We offer standard products with a pitch range from 10μm to 1500μm.
We can support size cutting within 4 inches.
Applications
Fused Silica Hexagonal Microlens Arrays Applications
- Laser Beam Shaping and Collimation In high-power lasers, uneven energy distribution in the laser spot affects processing quality. Fused silica hexagonal microlens arrays can refract, focus, homogenize, and collimate laser beams, achieving more uniform energy distribution and stable processing.
- Optical Communication In optical communication systems, fused silica microlens arrays serve as interfaces to improve fiber coupling efficiency and reduce insertion loss. They are used in high-speed optical modules, WDM modules, and photonic integrated devices between chips and fibers.
- 3D Sensing and Imaging In devices such as 3D facial recognition and AR/VR, microlens arrays enable beam shaping, speckle generation, and optical path homogenization, enhancing image clarity and accuracy, thereby improving 3D perception capabilities.
