Zinc Selenide Focusing Lens
The Zinc Selenide focusing lens produced by GiAi has domestic and imported options. The lens produced can withstand high power density, and the surface film is firm, not easy to fall off, and resistant to wiping. After double-sided anti-reflection coating of zinc selenide, the transmittance in the common working band of CO2 laser industry of 10.6μm can reach 99%.
Product Code:GA-ZSFL
Application:
Zinc Selenide focusing mirrors are widely used in the CO2 laser processing industry, including laser cutting, engraving, marking, drilling and other laser systems.
Our advantage:
Our products are optimized from the perspective of diffraction and aberration, and we have launched a series of products that minimize the actual focused spot diameter under the same focal length. It can be individually designed and processed according to the different requirements of the user's focal length, back focal length, lens diameter, and incident light diameter.
