we’re here to all your questions
Here are the most common questions about COB VCSELs. If you have additional inquiries, feel free to consult our support specialists at no charge.
What distinguishes COB VCSEL from traditionally packaged VCSEL?
COB (Chip On Board) involves directly bonding the VCSEL chip onto the packaging substrate, followed by array configuration and optical processing. Compared to traditional single-chip packaging, COB significantly enhances integration density, reduces size, improves thermal performance, and lowers packaging costs. It is highly suitable for high-power, multi-channel applications.
What is the lifespan and reliability of COB VCSELs?
Thanks to direct mounting and simplified interconnect paths, COB VCSELs reduce solder joints and connectors, lowering failure risks. Combined with VCSELs’ inherent stability under varying temperatures and currents, they achieve stable operation exceeding 20,000 hours—or longer—with proper thermal management.
What are the primary application scenarios for COB VCSELs?
Typical applications include 3D sensing and facial recognition, LiDAR, industrial ranging and vision inspection, optical communications, medical and life sciences, AR/VR interaction, and other scenarios demanding high-power, highly consistent beams and miniaturization.
