Abstract
A method of manufacturing a microlens array comprising forming microlenses by dropping or injecting to a plurality of through holes formed on a substrate a liquefied lens material so as to dispose the lens material at each of the through holes, the lens material being curable and has a predetermined transmittivity and a predetermined viscosity.
Claims16
A method of manufacturing a microlens array comprising dropping or injecting a liquefied lens material into a plurality of through holes formed on a substrate so as to dispose the lens material at each of the through holes, the lens material having a predetermined transmittivity and a predetermined viscosity, and
- curing the lens material within the substrate to form the microlens array with the lens material extending through the through holes above and below the substrate.
A method of manufacturing a microlens multilayer array comprising:
- providing a first substrate having a first plurality of first through holes;
- providing a second substrate having a second plurality of second through holes;
- dropping a liquefied lens material into the first plurality of first through holes formed on the first substrate;
- curing the liquefied lens material, the cured lens material having an optical axis;
- dropping a liquefied lens material into the second plurality of through holes formed on the second substrate so as to dispose the lens material at each of the through holes;
- curing the liquefied lens material, the cured lens material having another optical axis;
- aligning the first substrate to the second substrate so as to align the optical axes of the microlenses of the first substrate with the other optical axis of the second substrate;
- and
- forming the finished microlens multilayer array.
