SL-690-35 — High-Performance, Highly Reliable 3D Structured-Light Laser

Wavelength: 525 nm Wavelength Tolerance: +5/-5 Power: 5，10，20，25，50，75

Coherent's StingRay diode-based structured-light pattern lasers offer flexibility, easier focusing, excellent output capability and longer life, enabling faster, more accurate 3D machine-vision system construction. They are described as the industry's first standard products with brightness nonuniformity below ±5%. Uniformity simplifies image postprocessing and improves measurement accuracy/speed. Adjustable-focus optics focus the laser onto planes at different distances. The lens mechanics also allow Dynamic Line Balancing to avoid uneven brightness when mounted at an angle.

The source describes highway monitoring nodes every2km in a chain: an intermediate power failure disconnects downstream nodes, preventing evidence retrieval after incidents. It cites an above98% highway/public-security monitoring uptime requirement. FIBERWDM 瑞东科技's FW-OLPB automatically detects protected-node power and instantly bypasses failed nodes optically, maintaining connectivity. It suits highway/tunnel surveillance and improves downstream equipment availability. In a single-fiber A–C–B chain, C failure interrupts downstream communication. Adding OLPB bypasses C. The stated normal path is A equipment → A interface (protection module) → L interface (C equipment) → R (protection module) → B interface (protection module) → B equipment. On C power loss, the path becomes A equipment → A interface → B interface → B equipment. Optical switching automatically changes the default path and carries traffic during power interruption, preserving A–B communication. Restored C power automatically returns normal A–C–B operation. Diagram references in the cached description illustrate these states.
