⚠️ Critical Integration & Safety Warning:
This is a CLASS 4 LASER MODULE. It emits invisible near-infrared radiation (808nm) that can cause severe eye injury and skin burns, and can ignite materials. It must be integrated into a properly interlocked, safety-rated enclosure (Class 1 system) by qualified personnel. Operation requires a compatible Constant Current Laser Diode Driver and an Active Chilled Water Cooling System. Failure to provide adequate cooling will result in instant, catastrophic damage. Appropriate Laser Safety Goggles for 808nm are mandatory during setup, alignment, and maintenance. The seller is not liable for damage or injury resulting from improper integration, cooling failure, or misuse.
