Monolithic compound lens

A method of fabricating a lens includes dispensing a first liquid optically-transmissive material into a first mold cavity and then curing the first liquid optically-transmissive material to form a first region the lens having a first refractive index and an optical interface surface. A second liqui...

Beschreibung
Zusammenfassung:	A method of fabricating a lens includes dispensing a first liquid optically-transmissive material into a first mold cavity and then curing the first liquid optically-transmissive material to form a first region the lens having a first refractive index and an optical interface surface. A second liquid optically-transmissive material then dispensed into a second mold cavity over the optical interface surface while the first region of the lens is disposed within the second mold cavity. The second liquid optically-transmissive material in the second mold cavity is cured to form a second region of the lens having a second refractive index. An optical interface between the first region and the second region conforms to the optical interface surface.
