Focussing Lens D37 F150

The working principle of focussing lens is similar to that of collimating lens except that the convex surface is in the opposite direction. Due the short focal length, the laser is very concentrated at the focus. This lens reduces the divergence angle of the light, converging the laser beam on the small focal point. To maintain a high transmittance, it is crucial to keep the focusing lens clean.

Short-focus focusing lenses can shorten the distance between the cutting head and the material, making it more, to the intrusion of molten residue into the laser head. It’s helps in laser beam focus, cutting efficiency, material compatibility, good precision and accuracy.
