Zinc selenide focus lens are widely used in CO2 laser process, including cutting, drilling,
carving & other laser system. With the imported material, our products can withstand high power
density; and the film is solid, with which the lens are resistant to wipe. Because of the double-side film, the filterability of the light (the wavelength is 10.6μm) can reach 99%.
Clean lens, must be very careful, before cleaning,
please look at the following notice:
1. Take lens must wear gloves or rubber gloves, because the dirt and oil droplets
on the hand can contaminate the lens, cause performance decline.
2. Don´t use any tool to take the lens, such as tweezers, etc.
3. Put the lens on paper, in order to avoid damage.
4. Don´t put the glasses on rough or hard surface, infrared lens is easy to scrape.
5. Pure gold or pure copper surface don´t clean and touch.
