Description
🔍 20mm Laser Focal Lens – Choose the Right Focus for Engraving or Cutting
This 20mm Laser Focal Lens is available in four different focal lengths to match your cutting or engraving needs. Designed for CO₂ laser systems, it delivers high precision and energy concentration right where it counts.
The focal length of a lens is the distance from the lens to the point where the beam narrows to its highest intensity — the focal point. This is the spot where your laser has the most power, which is why picking the correct lens matters.
