Targeting semiconductor manufacturing and repair applications, complete laser micro-machining heads have integrated DPSS Jewel ND:Yag laser, uni-body all-in-one form factor, as well as mechanical and optical design. Models offer dual or multiple wavelengths, independent or dual attenuation, and fixed or adjustable polarization. Modular design, featuring swappable resonators and diodes with minimal alignment or adjusting, decreases downtime.
