Microlens Arrays Emerge as Low-Cost Option.(Brief Article)

From: R & D | Date: March 1, 2000| Author: | Copyright information

Microlens arrays are small replicated optical elements consisting of arrays of microscopic lenslets tens to hundreds of micrometers in diameter. Each lenslet presents a high-quality optical surface that is equivalent to an ordinary single-element lens. Such arrays have been used in a wide variety of spatial-filtering applications ranging from lentographs to confocal microscopes.

When used as a light source, the microlens array collects light from a collimated beam and focuses it to an array of small, bright points at the focal plane. Each lenslet focuses the light it ...
