Abstract
A method of forming a compound lens includes molding multiple lens elements to form a compound lens. The multiple lens elements are molded from polymers that provide each lens element with the desired optical properties. First and second lens elements formed from a first polymer can be molded around a central, third element formed from a second polymer that differs from the first polymer by the addition of a cyclic substituent group. During curing of the lens elements, cross-links are formed between the first and second polymers to form an molded, integrally formed compound lens.
Claims20
A method of forming a compound lens comprising:
- providing a mold having a mold cavity corresponding to a shape of the compound lens;
- co-molding first and second lens elements each comprising a first polymer within the mold cavity, the first lens element being spaced apart from the second lens element;
- and
- molding a third lens element comprising a second polymer within a portion of the mold between the first and second lens elements,
- wherein the third lens element adheres to each of the first and second lens elements to form an integrally molded compound lens, and
- wherein the second polymer differs from the first polymer by the addition of a cyclic substituent group, and
- wherein cross-linking between the first and second polymers occurs during curing of the third lens element between the first and second lens elements.
A method of forming a compound lens comprising:
- providing a mold having a mold cavity corresponding to a shape of the compound lens;
- forming a first lens element comprising a first polymer in a first portion of the mold;
- forming a second lens element comprising a second polymer in a second portion of the mold;
- and
- forming a third lens element comprising a third polymer in a third portion of the mold, the third portion disposed between the first and second portions of the mold,
- wherein the first polymer and the second polymer adhere to the third polymer to form an integrally molded compound lens,
- wherein at least one of the first, second, or third polymers includes a cyclic substituent group, and
- wherein cross-linking between the first and third polymers and the second and third polymers occurs during curing of the third lens element between the first and second lens elements.
