The LBTek flat microlens array is a planar optical element built on diffraction optics principles using liquid crystal polymers. It comprises a polymer film and a single N-BK7 window plate designed for laser beam homogenization and shaping applications.
The device utilizes arrayed phase distribution on the liquid crystal polymer film to achieve microlens array functionality. By adjusting phase periods and contours of individual microlens units, engineers can flexibly manage both divergence angles and spot shapes to satisfy diverse beam shaping requirements.
Key Features
- Polarization-dependent operation with opposite outgoing polarization to incident state
- Planar design based on diffraction principles, eliminates spherical aberration
- Single-wavelength optimization with minimal aberration
- Anti-reflection coating ensuring high transmittance and diffraction efficiency
- Extensive customization capabilities for specialized specifications
