1550nm 5W C mount Diode Laser in Eye-Safe Range Finding：
The 1550nm wavelength falls within the eye-safe infrared region, meaning it is much less likely to damage human eyes compared to shorter near-infrared wavelengths (e.g., 808nm or 1064nm). This makes it highly suitable for laser range finding and LiDAR systems, particularly in environments where human exposure is a concern.
Why 1550nm for Range Finding?
1：Eye Safety Compliance: At 1550nm, the laser light is strongly absorbed by the cornea and does not reach the retina, allowing for higher output powers (up to several watts) while still meeting IEC/ANSI Class 1 eye safety standards.
2：Higher Power = Longer Range: With 5W output, the laser can achieve greater detection distances and higher resolution for accurate measurements.
3：Low Atmospheric Scattering: 1550nm has favorable propagation characteristics through dust, fog, and other airborne particles compared to visible or shorter near-IR wavelengths.
4：Reduced Interference: This wavelength band has less background noise from ambient sunlight, improving detection reliability.
