Lens assembly for fiber-optic communication system

摘要

A lens assembly is used in a fiber-optic communication system, and includes a substrate and at least one lens unit formed on the substrate. The lens unit has first and second surfaces, a first light-transmissive region proximate to the first surface, a second light-transmissive region proximate to the second surface, a light attenuation region located between the first and second light-transmissive regions, and an optical axis passing through the first and second light-transmissive regions and the light attenuation region. The light attenuation region has at least one attenuation layer formed with multiple carbonized spots using a high-energy beam such that the light transmittance of the lens unit is not greater than 70%.

1. A lens assembly for a fiber-optic communication system, said lens assembly comprising:
a substrate; and at least one lens unit that is formed on said substrate, and that has a first surface, a second surface, a first light-transmissive region proximate to said first surface, a second light-transmissive region proximate to said second surface, a light attenuation region located between said first and second light-transmissive regions, and an optical axis passing through said first and second light-transmissive regions and said light attenuation region, said light attenuation region having at least one attenuation layer that is formed with a plurality of carbonized spots using a high-energy beam such that the light transmittance of said lens unit is not greater than 70%, wherein said optical axis passes through a geometric center of said first light-transmissive region, and a geometric center of said second light-transmissive region.
