We can see a big difference from the title, the same is the focus lens, a CVD zinc selenide focusing lens, a PVD zinc selenide focusing lens, the biggest difference between these two focusing lenses is the growth of zinc selenide material Different ways: one is CVD growth mode, and one is PVD growth mode. These two growth methods determine the quality and cost of zinc selenide focusing lenses are very different.
The CVD zinc selenide material has less impurity content, the production process is more strict, and the production cost is much higher than the PVD zinc selenide material. CVD zinc selenide focusing lenses are easier to dissipate heat during use, and the service life will be longer than PVD zinc selenide focusing lenses under the same conditions.
