Tips:
- Focus Lens Diameter: Higher power lasers require larger diameter lenses to prevent thermal overload.
- Focal Length: Focal length affects both spot size and depth of focus. In general, a shorter focal length will produce a smaller focused spot and a shorter depth of focus.
- How to install: Convex Face to Laser and Concave Face to Carving.
