SELFOC (Self-Focusing) microlenses are a type of optical component that utilize a unique design to focus light. They are typically made from materials such as glass or optical polymers and are characterized by a gradient refractive index (GRIN) structure. This means that the refractive index of the lens material changes gradually from the center to the edge, allowing the lens to focus light without needing a curved surface. **Key features of SELFOC micro lenses:** 1.
