A microlens array is an optical device that has lots of tiny lenses. It can be used to make a light field display.
A microlens array is used in Lytro's cameras.[1]
Each lens in the array has its own optical axis. However, when the array is viewed as a cohesive unit, the lenses form a shared main optical axis.[2]
Thorlabs advertises the sale of microlens arrays as of 2024.[3] Thorlabs has claimed that their lenslet arrays are formed using photolithographic techniques.[3]
The side with the roundings should generally face towards the source of the light.
Microlens arrays can be produced using microfabrication techniques.
Dimensions
Microlens arrays have been produced with a distance between microlenses of about 125 microns, which is 1/8 of a millimeter.[4][3]
To make a plenoptic microlens based display, each microlens should be at the minimum 200 pixels wide and 200 pixels long.
