Low Numerical Aperture Optical Collimation Material
This light collimation material is a two-dimensional optical waveguide array formed by regularly arranged micron-scale light guides. Adjacent waveguides have excellent optical insulation characteristics, enabling optical images to penetrate transparent layers of more than 3mm without image quality deterioration, while effectively blocking ambient stray light from entering the image sensor and ensuring the accuracy of image signal extraction. The product has advantages such as large-area full-screen fingerprint unlocking, live fingerprint recognition, FBI and GA safety certification, and ultra-thin 0.12mm thickness, with customizable sizes.

A microlens array (MLA) is a high-precision optical component composed of hundreds or thousands of tiny, uniformly arranged micro lenses on a single flat substrate. Unlike traditional single lenses that focus one light beam, a microlens array can split, homogenize, and reshape light on a micro scale. It is widely paired with VCSELs, lasers, and image sensors, becoming a core part of modern miniature optical systems.
