Plastic Lenses: Injection molding of optical-grade resins enables complex aspheric shapes, high volume production, and low cost. Suitable for smartphones and consumer cameras but limited in thermal stability and durability compared to glass. It can be confusing for those new to the field. When discussing optical modules, what are we actually talking about? This article aims to delve into. As optical modules are employed for high-speed data transmission and optoelectronic conversion, the manufacturing quality of their PCBs directly impacts the performance, stability, and reliability of the optical modules.
