Method of manufacturing a lens assembly by means of a replication process, wherein the following steps are carried out i) introducing a first, liquid, UV curable composition (2) into a first mould (1) provided with regularly spaced-apart cavities (6), 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, in) applying a second, liquid, UV curable composition (5) to the first composition cured in step ii), iv) placing a second mould (4) on the second composition (5) applied in step iii), which second mould is provided with regularly spaced-apart recesses (7), 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 lens element is the negative of that of the recesses, and vi) possibly removing the first and/or the second mould.
A method of manufacturing a lens assembly by means of a replication process, characterised in that the following steps are carried out
A method according to any one or more of the preceding claims, characterised in that a film is arranged over the uncured first composition prior to carrying out step ii), which film seals the first composition present in the cavities of the first mould.
A method according to any one or more of the preceding claims, characterised in that the first lens element has a refractive index different from that of the second lens element.
A method according to any one or more of the preceding claims, characterised in that step i) is carried out in such a manner that the first, UV curable composition flows out over the first mould, whilst the parts present between the the cavities are also provided with the first, UV curable composition.
A method according to any one or more of the preceding claims, characterised in that steps iii) and iv) are carried out in such a manner that the second, UV curable composition flows out over the second mould, whilst the parts present between the recesses are also provided with the second, UV curable composition.
