Lightobject's in-house Auto-focus laserhead for non-metal cutting. Ideal for big CO2 Laser cutters that have the intentions to mainly use it for cutting and little engraving. No more fails cutting through warped material or worrying about the laser head out of focus cutting. 
Is DSP controller dependency?  Ans: No, it is a stand alone unit and it works on most laser machines.
Note: This is a DIY laserhead and NOT a plug-and-play. This means for this laserhead system to work as intended the user has to take into account the work that will have to be put into making the laser head work, adjusting the mirror mounts to account for the new laserhead mount is one such example.
