Q&A

Q1:According to my laser power, how should I choose the diameter of this CVD focusing lens?

    A1:Focusing lenses with different diameters can withstand different laser output. Theoretically speaking, dia.12mm can withstand 30-50W, dia.15mm can withstand 50-80W, and dia.18/19/20mm can withstand 50-180W, dia.25/28mm can withstand 150-500W laser output power.
