A microlens array is a lens array that has lenses less than a few millimeters wide. It is an important component of light field cameras and some types of light field displays.
It can be used to make a microlens-based light-field display.
The lenses are best measured using micrometers, also known as microns.
Lens arrays can be produced using microfabrication techniques, in particular photolithographic techniques.[1]
Lens arrays have been manufactured at the wafer level by Lytro.[2]
Lens arrays have been produced with a distance between lenses of about 125 microns, which is 1/8 of a millimeter.[3]
Production[edit]
Microlens arrays can be produced using the photoresist reflow technique.[4]
Diamond point turning can be used to form microlenses.[4]
Ion beam etching can be used to correct a lens profile to form aspheric lenses.[4]
