Overview & Key Features:
- High output options: Beam compression technology combines multiple diodes to deliver higher optical power for faster cutting and deeper engraving.
- Air assist system: Built-in air airway and optimized nozzle reduce burn marks, remove debris and fumes, and improve cut edge quality.
- Cooling & reliability: Dual fan cooling and temperature monitoring with alarm protect the module and extend service life.
- Red crosshair positioning: Integrated red cross line helps align workpieces for accurate secondary cuts and engraving.
- Protective cover: Removable protective shield filters blue light for safer operation without goggles (use of appropriate laser goggles still recommended for full protection).
- Wide compatibility: Designed for many DIY laser engraver platforms and hobby machines; check controller compatibility or provide controller photo for connection guidance.
Performance Examples (for reference):
- 20W (approx.) module: 12 mm basswood plywood (0.47 in) — 100 mm/min (≈ 3.94 in/min) one pass; 15 mm black acrylic (0.59 in) — 15 mm/min (≈ 0.59 in/min) one pass; 9 mm MDF (0.35 in) — 100 mm/min in 2 passes.
- 10W / 8W class module: 8 mm bass plywood (0.31 in) — up to 120 mm/min (one pass); 5 mm plywood (0.20 in) — 50 mm/min (one pass).
- 5W module: Cuts 4 mm plywood (0.16 in) at ~190 mm/min (one pass); high precision engraving down to 0.08 mm resolution.
Benefits: Improves cut cleanliness, reduces post-processing, enables faster throughput on thin-to-medium stock, and simplifies alignment with the built-in crosshair and removable protective cover.

Safety Notes:
This is an electrical laser module. Use the correct 12V power supply with appropriate current rating, disconnect power before installation or maintenance, and ensure proper wiring to avoid short circuits or fire hazards.
Laser radiation hazard: avoid direct eye and skin exposure to the laser beam. Always wear appropriate laser safety goggles rated for 450 nm when the protective cover is removed or when high-power operation may allow stray beams. Use the removable protective shield when possible and operate the laser in a controlled area away from bystanders and children.
Use adequate ventilation or fume extraction when cutting materials (especially plastics) and keep flammable materials away from the work area. Monitor module temperature and cooling; the unit includes temperature alarm features—stop operation if overheating occurs and allow the module to cool before resuming work.
