Avantier Microlens Arrays: Precision in Every Lens
Avantier specializes in the design and manufacturing of high-performance microlens arrays (MLAs)—compact optical components engineered to deliver precise beam shaping, uniform illumination, and exceptional efficiency.
Microlens arrays, also known as microstructure lens arrays, consist of 1D or 2D grids of miniature lenses that collectively manipulate and homogenize light. They are indispensable in LiDAR, biomedical imaging, AR/VR systems, projection displays, and laser beam shaping, where reliability and accuracy are mission-critical.

Technical Resource
What is a Microlens Array?
A microlens array is a miniature optical device composed of thousands to millions of tiny lenses on a substrate, arranged in 1D or 2D grids. Each microlens functions independently yet contributes to collective light regulation, enabling beam homogenization, focusing, and advanced optical manipulation.
Lens Arrangements
- Rectangular Grid: Ideal for alignment with pixel arrays
- Hexagonal Close-Pack: Maximizes fill factor for circular lenses
- Radial Gradient: Reduces edge distortion, enables annular beams
- Randomized: Suppresses speckle noise in holography and laser displays
Classification
- By Optical Principle: Refractive, diffractive, or hybrid
- By Material: Glass (durable, UV–IR range), polymers (cost-effective), semiconductors (photoelectric integration)
- By Functional Form: Spherical (focusing), cylindrical (fly’s eye condensers), aspheric (aberration correction)
Manufacturing Methods
- Photolithography (cost-efficient mass production)
- Femtosecond laser direct writing (high flexibility, free-form designs)
- Nano-imprint lithography (complex surfaces, scalable)
- Micro injection molding (polymer arrays)
- 3D printing (free-form, early-stage applications)
Innovative Applications
- Autonomous Driving: LIDAR beam control, IR/visible multispectral imaging, head-up display enhancement
- Imaging Technology: Smartphone cameras, 3D face recognition, medical endoscopy
- Laser Processing: Solar cell etching, EUV chip lithography, precision display cutting
- Biomedical Devices: Lab-on-a-chip diagnostics, gene detection, neuroimaging implants
- Display & Lighting: Adaptive headlights, glare-free projection, surgical shadowless lighting
