Features
- The lens features a hexagonal aperture, which offers more uniform beam distribution and higher fill factor compared to square or circular apertures.
The hexagonal array layout ensures even light field distribution and enhances spatial resolution, making it especially suitable for homogenized illumination. - Monocrystalline silicon is used as the substrate material, known for its high purity, hardness, and low thermal expansion, making it ideal for infrared applications.
Lens apertures range from 120 µm to 1000 µm, supporting multi-channel integrated designs. - Focal length ranges from 0.55 to 40 mm, accommodating various working distances.
- Surface coating is optimized for near-infrared at 1550 nm, a typical wavelength for telecom and sensing applications.
Applications
- Silicon Hexagonal Microlens Arrays Application: Infrared Imaging Systems. Traditional square arrays have a low fill factor. Integrating microlens arrays on the surface of infrared detectors, the hexagonal honeycomb structure enables focusing and beam alignment, effectively covering more active pixels.
- Laser Beam Shaping: Multimode lasers or VCSEL arrays often suffer from uneven beam profiles and low edge energy. Hexagonally arranged microlens arrays can homogenize the laser beam and can be used in combination with microlens posts, DOE, etc.
- Fiber Coupling: Multi-channel fiber systems require high-precision beam focusing and collimation. Aligning the microlens array with multi-core fiber interfaces or fiber arrays enables efficient one-to-many or many-to-many coupling.
