SELFOC® LENS PLATE
Smaller system size, easy placement, aerial display
SLP (SELFOC® Lens Plate) is a lens plate in which lenses are arranged in a two-dimensional direction by applying the technology of SELFOC® lens array (SLA). An aerial image can be displayed by combining it with a liquid crystal display.
The remarkably short working distance (L) of SLP, which is only a few mm, allows a significant reduction in the overall size of the system.
In addition, since SLP forms an erect 1:1 image, the lens plate does not require any other lenses or mirrors in the system, unlike ordinary lenses. With this feature, SLP produces a very simple and competitively-priced optical system.

Because SLP its does not require any specific lens holders, its placement is extremely simple and easy compared with ordinary lenses.
Since SLP forms an aerial image, it can be used in touchless interface solutions.
