Abstract
The optical device comprises a first substrate (SI) comprising at least one optical structure (1) comprising a main portion (2) and a surrounding portion (3) at least partially surrounding said main portion. The device furthermore comprises non-transparent material (5, 5a, 5b) applied onto said surrounding portion. The opto-electronic module comprises a plurality of these optical devices comprised in said first substrate. The method for manufacturing an optical device comprises the steps of a) providing a first substrate comprising at least one optical structure comprising a main portion and a surrounding portion at least partially surrounding said main portion; and b) applying a non-transparent material onto at least said surrounding portion. Said non-transparent material is present on at least said surrounding portion still in the finished optical device.
