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.<ref name="u455">{{cite web | title=Microstructure Lens Arrays | website=Laser Focus World | url=https://www.laserfocusworld.com/directory/finished-optics-coatings-components/lens-arrays/product/14303094/avantier-inc-microstructure-lens-arrays}}</ref>

The side with the roundings should generally face towards the source of the light. In a display, this means that the user's eye faces the flat side of the array, and the underlying display faces the side with the roundings.

To make a plenoptic microlens based display, each microlens should be at the minimum 200 pixels wide and 200 pixels long.
