Opto Engineering^® supplies a comprehensive range of projection patterns compatible with our LED illuminators.
PT projection patterns can be either laser-engraved, with 50 µm geometrical accuracy, or photolitography-engraved for more demanding applications (2 µm accuracy).

Custom geometry patterns can also be provided upon request.
