The Difference between Focusing Lens Materials

Focusing lens of Kinghang laser is mainly divided into: cvd zinc selenide focusing lens, pvd zinc selenide focusing lens and germanium focusing lens. There is also a kind of gallium arsenide focusing lens, but we do not produce it. What is the difference between these four different materials of focusing lenses?

First of all, cvd zinc selenide focus lens and pvd zinc selenide focus lens are both zinc selenide material, the difference is that the production method of zinc selenide material is different, so there is a clear difference between cvd and pvd.

JingHang laser has advanced coating process, so that there is no difference in the effect of the two materials of focusing lens below 200w. That is to say, used on CO2 laser below 200w, whether you choose cvd or pvd zinc selenide focusing lens is the same.

Secondly, germanium focusing lens material is very expensive, the current domestic CO2 laser industry can no longer afford its cost, only in the laser engraving machine used. Laser engraving machine focus lens is 12mm in diameter, which can greatly reduce the cost of germanium focus lens.

Again, gallium arsenide focusing lens is an obsolete product, due to the emergence of zinc selenide focusing lens, more and more industries are no longer using gallium arsenide focusing lens, and use zinc selenide focusing lens instead. The main reason is that Gallium Arsenide focusing lens is not as effective as Zinc Selenide focusing lens.
