Semiconductor Laser Collimation Solution
Semiconductor laser chips emit light with large fast-axis divergence, requiring fast-axis compression and collimation in many applications. Limited internal space makes collimating-lens assembly difficult. Fujin offers assembly services to address this problem. Its complete internally developed processes attach a fiber cylindrical lens in front of the chip's emitting facet, adjust focus and collimation, and deliver the assembly, reducing customer process-development time and cost.
