  Available in 808nm, 850nm, 940nm, 980nm, and 1064nm to suit diverse applications
• High optical output power
  Ranging from 1W to 3W, ensuring strong and consistent signal performance
• Low beam divergence
  Typically between 15°–25°, enabling better focusing and long-distance transmission
• Energy-efficient operation
  Optimized electro-optical conversion reduces power consumption while maintaining performance
• Compact SMD 3535 package
  Measuring just 3.5mm × 3.5mm, ideal for space-constrained designs
• High reliability and long lifespan
  Less than 5% light decay after 1,000 hours and under 20% after 50,000 hours
• Efficient thermal management
  Ceramic substrate design ensures stable heat dissipation for continuous operation
