-'''Microlens array'''
+A [[microlens array]] (MLA) is a planar grid of microscopic refractive elements—typically tens to hundreds of micrometres in diameter—fabricated on a common transparent substrate.<ref name="Paschotta">R. Paschotta, ''RP Photonics Encyclopedia'', article “Microlens Arrays”, accessed 26&nbsp;April&nbsp;2025.</ref>  Each lenslet focuses or collimates incoming light, enabling compact optical functions that would otherwise require bulky macroscopic optics.  MLAs commonly appear in [[Virtual reality|VR]] and [[Augmented reality|AR]] displays, image sensors, illumination systems, and wavefront sensors.
