High-Power Multi-Mode VCSEL Chips
Use our 940 nm laser diodes in high-volume mobile applications (e.g., proximity sensing, auto-focus) where laser power and economy are the most important considerations.
These laser chips operate in multiple transverse modes enabling a very high power-to-size ratio as well as excellent reliability. They generate a circular beam with a doughnut far-field intensity pattern. Their typical output power (at 25°C) is 20 mW.
