Why is Focusing Necessary?
For Laser engraver, lenses are often used to focus the laser beams. The laser beam will be refracted or reflected when passing through the lens, its direction and focus will then be altered.
Without proper focusing, the laser beam may defocus, bringing unclear, blurry, or uneven engravings.
Proper focusing will ensure the laser beam gathers on the right point, concentrating its energy at the focus for high-quality engravings.
Focusing Range of LP2
See the table below:
Focusing Range from the Base Plate
110mm - 230mm
Supported Material Thickness
the minimum distance from the field lens to the Base Plate is 110mm.
the travel distance of the electric stand is 120mm.
LP2’s recommended focusing distance is 110mm.
Press the electric stand button to rise or drop 1mm.
press and hold for continuous rise or drop.
In practical use, two focusing methods are available based on different scenarios:
Focal Ruler Focusing, Measurement Focusing, Protection Cover Focusing
1.Focal Ruler Focusing
Position the engraving object, lower the L-shaped distance gauge, adjust the height of the electric stand, let the bottom of the distance gauge contacts the surface of the object to be engraved, and retract the distance gauge after completing the measurement
Measure the distance between the field lens and material to be engraved with a ruler, then adjust the height of electric stand until the lens is 110mm from the material.
3.Protection Cover Focusing
Install the protection cover, and adjust the electric stand’s height right until the cover’s bottom reach the material to be engraved. Focusing is then successful.
