Q&A

    Q1:PVD is a focusing lens, and CVD is also a focusing lens. Why are the prices so different?

A1:PVD materials are comparable to CVD materials, and there is no difference in use. Expect your machine to have a large power (above 200W). Otherwise, from the perspective of cost performance, PVD focusing lenses will be much better than CVD focusing lenses. Almost all features and functions reach a high degree of agreement.
