1. A wafer-level optical structure, comprising:
- an optically transparent wafer;
at least two optical lens sets disposed on said optically transparent wafer, wherein each of said at least two optical lens sets comprising a lens integrated with a residual layer;
at least one trench disposed above said optically transparent wafer, wherein said at least one trenches is disposed between two adjacent said at least two optical lens sets to divide adjacent said at least two optical lens sets;
at least one spacer disposed on said optically transparent wafer, wherein said at least one spacer is disposed between adjacent said at least two optical lens sets to be correspondingly and partially disposed in one of said at least one trench; and
an adhesive disposed inside one of said at least one trench to at least partially fill the trench and in direct contact with one of said at least one spacer.
