Rofin has incorporated the fast focussing unit (FFU) into its Powerline laser markers, which facilitates users to make alterations in marking height of a maximum of 22mm in a duration of 15 minutes. The expansion ratios are 1:2.8 and 1:5.

This feature is suitable for any single-head system that is equipped with a Visual Laser Marker (VLM). The FFU’s control is done through the VLM software’s layer function. Models that are compatible start from the software version VLM 3.6.

Since the FFU is positioned between the laser and the galvo head, there is no necessity to move either of them while adjusting the focal distance, thus saving a considerable amount of time.

With a maximum absolute range of 22mm with a flat field lens f = 254; and 14mm with a flat field lens f = 160mm, the travel time between the lower and the upper positions is 15 minutes.

The FFU is available from Laser Resources .
