Fabricating a Lens Assembly

A device comprising:

• an image sensor;
• and
• a lens assembly configured to focus light onto the image sensor, the lens assembly comprising:
• a tube, the tube optically transparent to a first wavelength of ultraviolet (UV) light;
• a first optical element fabricated from a volume of UV curable optical polymer conveyed into the tube, wherein the UV curable optical polymer has a first refractive index, and wherein an outer boundary of the first optical element is cured to the tube;
• and
• a second optical element fabricated from a second optical polymer having a second refractive index different than the first refractive index.

A lens assembly comprising:

• a tube, the tube optically transparent to a first wavelength of light;
• an optical element, wherein the optical element is fabricated from a volume of optical polymer conveyed into the tube, the volume of optical polymer bonded to an inside shape of the tube, the volume of the optical polymer having a first refractive index;
• and
• at least one other optical element, the at least one other optical element fabricated from a second optical polymer conveyed into the tube and bonded to the inside shape of the tube, the second optical polymer having a second refractive index.
