Claim:
A method of manufacturing a lens assembly by means of a replication process, characterised in that the following steps are carried out i) introducing a first, liquid, UV curable composition into a first mould provided with regularly spaced-apart cavities, ii) curing said first composition by UV radiation so as to obtain a first lens element comprising lenses arranged beside each other, wherein the surface of the obtained lens element is the negative of that of the cavities, iii) applying a second, liquid, UV curable composition to the first composition cured in step ii), iv) placing a second mould on the second composition applied in step iii), which second mould is provided with regularly spaced-apart recesses, in such a manner that said recesses will fill with the second composition, v) curing the second composition by UV radiation so as to obtain a second lens element comprising lenses arranged beside each other, wherein the surface of the obtained second lens element is the negative of that of the recesses, and vi) possibly removing the first and/or the second mould.
