Title: MULTI-CHANNEL LENS STRUCTURE
Abstract:
A multi-channel lens structure, comprising: a circuit board (1), and a plurality of laser chips (2) and a plurality of lens assemblies (3) disposed on the circuit board (1), the lens assemblies (3) corresponding one-to-one to the laser chips (2), the lens assembly (3) comprising a lens array (31) provided to cover the laser chip (2), a jumper (32) provided to cover the lens array (31), and a reflector (33) disposed on the jumper (32) and located directly above the laser chip (2); the jumper (32) is provided with an optical fiber insertion slot (321) for accommodating optical fiber (4), the optical fiber insertion slot (321) being located on one side of the reflector (33), and the inner port of the optical fiber insertion slot (321) directly facing the reflection direction of the light emitted by the laser chips (2) and reflected by the reflector (33). By means of packaging, sequentially from the bottom to the top, the lens array (31), the jumper (32), and the reflector (33) on the upper side of the laser chip (2), the packaging of the channel lens structure is simple and convenient, and the optical tolerance thereof is increased.
