Introducing Microlens Arrays
What if you could bring the power of nature’s compound eyes to your optical assembly— in a tiny package 10 mm x 10 mm? It turns out, you can! Whether you need to homogenize light from line-narrowed excimer lasers or high power LEDS, microlens arrays can give you the high efficiency and non-Gaussian uniformity you need. These optical assemblies are composed of many tiny microlenses, arranged in a one or two-dimensional array.
What is a Microlens Array?
A microlens array is a miniature optical device, typically between several microns to a few millimeters in size, and composed of many even tinier lenses each placed to form a 1D or 2D array on a supporting substrate. Each microlens array may contain thousands or possibly even millions of tiny lenses, arranged to make a square grid, rectangle, or circle. Individually, each lens processes light as does a larger lens, but they also work together to accomplish complex light field regulation.
