Microlens Arrays
High-Performance Beam Homogenizers for LiDAR, Imaging, and Sensing Systems
At Avantier, we design and manufacture precision microlens arrays for cutting-edge optical systems. Available in both off-the-shelf and fully custom configurations, our microlens arrays deliver uniform beam shaping, enhanced light collection, and superior optical performance across applications like autonomous driving, 3D imaging, biomedical optics, and AR/VR projection.
What Is a Microlens Array?
A microlens array (MLA) is a two-dimensional grid of tiny lenses (lenslets) designed to manipulate and homogenize light. MLAs are used to:
- Shape and redistribute non-Gaussian beams
- Increase efficiency in optical coupling
- Enable wide-angle and compact imaging systems
Avantier’s MLAs are available in UV, visible, and NIR-grade substrates, with customizable pitch, focal length, and layout.
Types of Microlens Arrays
We offer two primary configurations optimized for different optical tasks:Fly’s Eye Condenser Arrays
- Dual-surface cylindrical lenslets
- Close-packed for uniform line or spot illumination
- Ideal for short working distances and large illuminated fields Applications: Laser projectors, industrial illumination, lithography
Square Grid Microlens Arrays
- High fill factor (up to 98%) elimiating zero-order hot spots
- Excellent for beam homogenization and shaping Applications: LiDAR emitters, laser beam shaping, endoscopic lighting
Microlens Arrays for Key Applications
Autonomous Vehicles & LiDAR
Microlens arrays are used in beam steering and depth-sensing modules to deliver precise, uniform illumination—critical for high-resolution mapping and object detection.Biomedical Imaging
MLAs allow compact camera modules and endoscopes to capture light more efficiently, enhancing contrast and brightness in low-light imaging.Wavefront Sensing & Adaptive Optics
Microlens arrays are key components in Shack-Hartmann sensors, enabling precise wavefront measurements in optical testing and astronomy.AR/VR and Projection Systems
Fly’s eye arrays are used to create uniform flat-top beams for displays, reducing glare and distortion in head-mounted displays and HUDs.Specifications
