A lens system comprising:
- a first lens region having a first refractive index;
- and
- a second lens region having a second refractive index, the first lens region being formed above and in direct contact with a portion of the second lens region and the second lens region has a ring shape.
A light projecting system comprising:
- a light source;
- and
- a lens structure for focusing light from the light source, comprising:
- a first lens region;
- and
- a second lens region, the first lens region being formed above and in direct contact with a portion of the second lens region and the second lens region has a ring shape.
3 more elements
A method of forming a lens structure, said method comprising:
- forming a first light condensing region having a first refractive index;
- and
- forming a second light condensing region having a second refractive index, wherein the first light condensing region is formed above and in direct contact with a portion of the second light condensing region, and wherein the second light condensing region is ring-shaped.
