Case Study: Custom Microlens Arrays Design

Microlens arrays are composed of multiple lens cells arranged on a glass, polymer, or metal substrate in 1D or 2D patterns. They are designed to manipulate light precisely, serving applications in lighting, imaging, and photonics.

By strategically arranging lenses, these arrays enhance beam control, improve system efficiency, and support advanced optical functions. Their substrate and configuration can be customized to meet specific application needs, making lens arrays a versatile tool in modern optics.

Case Study 1: Custom Microlens Array for Concept Demonstration

Project background:

A leading research laboratory required Avantier’s assistance in creating a custom microlens array (MLA) for a prototype in the advanced optics field. The MLA specifications included plano-convex, spherical, refractive lenses arranged in a hexagonal pattern with a 310 µm pitch, a near full fill factor, and a 541 µm radius of curvature. The footprint was to measure 30 mm × 10 mm, fabricated on a 100 µm thick N-BK7 substrate or equivalent. An aperture coating with a clear 250 µm diameter opening under each lens was also requested.
