Double or multi-focus optics
For simple use at the focusing head with scale to adjust the distance from 0 to 5 mm. With double or multi-focus optics, the laser beam is split before the lens into 2 or more focus points of equal strength. The spacing of the lines can be adjusted using a scale on the optics mounting.
This option can also be ordered as a retrofit. It can easily be adapted by the customer – without the assistance of a LANG LASER technician on site – to the existing focusing unit.
