Abstract
An optical fiber assembly includes a lens block with a plurality of beam expanding and collimating elements. Each beam expanding and collimating element includes a first lens and a second lens. The first lens includes a generally arcuate first lens surface and the second lens includes a generally arcuate second lens surface generally complementary in shape and in contact with the first lens. Each lens has a different index of refraction. An optical fiber assembly may include a housing with a plurality of beam expanding elements. A front portion of each beam expanding element has a generally planar front surface. A compliant layer is positioned on the generally planar front surface of each beam expanding element.
Claims16
An optical fiber assembly comprising:
- a body, the body supporting a lens block and a plurality of optical fibers, each optical fiber including an optical fiber axis, the optical fiber axes being generally parallel;
- and
- a plurality of beam expanding and collimating elements positioned in the lens block, each element being aligned with the optical fiber axis of one of the optical fibers and including a first lens and a second lens, the first lens including a generally arcuate first lens surface, the second lens including a generally arcuate second lens surface, the first lens surface and the second lens surface being generally complementary in shape and in contact with each other, each lens having a different index of refraction.
An optical fiber assembly comprising:
- a housing having a plurality of optical fibers, each optical fiber including an optical fiber axis, the optical fiber axes being generally parallel;
- and
- a plurality of beam expanding and collimating elements positioned in a lens block, each element being aligned with the optical fiber axis of one of the optical fibers and including a first lens and a second lens, the first lens including a generally arcuate first lens surface, the second lens including a generally arcuate second lens surface, the first lens surface and the second lens surface being generally complementary in shape and in contact with each other, each lens having a different index of refraction.
An optical fiber lens assembly comprising:
- a lens block, the lens block being formed of an optical grade polymer and including a plurality of first lenses integrally formed therewith;
- a plurality of generally parallel optical paths, each optical path including a beam expanding and collimating element, each element including one of the first lenses and a second lens positioned in the lens block, the first lens having a first index of refraction and including a generally arcuate first lens surface, the second lens having a second index of refraction and including a generally arcuate second lens surface, the first index of refraction being different from the second index of refraction, the first lens surface and the second lens surface being generally complementary in shape and in contact with each other.
