Expanded beam lens assembly

摘要

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.

1. 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.
