In this video I tear down a Domino D100+ Industrial Laser Coder!
It has a high speed Galvo Scan head complete with all the amplifiers the drivers and Silicon mirrors, and beautiful Zinc Selenide (ZnSe) F-Theta lens.
There is also a II-VI ZnSe Collimating lens and of course a 15W Synrad Carbon Dioxide Laser, with an unusual wavelength of 9.3 microns!

Is it all scrap, or can it be brought to life? Watch till the end to find out!
