Abstract

See full text

A display inspection system for inspecting a light beam emitted from a panel with pixels positioned at several focal planes is provided. The display inspection system includes a focus tunable lens adjustable in a focal distance for focusing at the panel, a first sensing unit for receiving the light beam, a reduced aberration optical system arranged between the focus tunable lens and the first sensing unit for focusing at the first sensing unit, and one or more optical elements placed within a back focal length of the reduced aberration optical system. The reduced aberration optical system comprises a first serial cascade lens group of a first aplanatic lens and a first doublet lens for correcting an optical aberration. The first aplanatic lens and the first doublet lens are co-configured that the back focal length is extended in a manner that the light beam is incident to the first sensing unit.
