Lens information detail :
Co2 laser Focus lens
Our lens feature
ZnSe has been made by means of import CVD from USA, and this material has low absorbance. The lens can withstand high power density and the surface coating is solid, not easy to fall off and wipe- resistant. After AR-coating has been coated on double-side of imported ZnSe, the transmissivity of the wavelength 10.6um, which is commonly used in CO2 laser industry, can reach 99.5%. We have optimized the design from two sides , diffraction and aberration have developed a series of products with minimum actual focal spot diameter in the case of the same focal length.
How to choice a suitable lens :
1.Firstly choice the diameter of lens ,
2.Secondly measure the focus length

Lens cleaning method
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.
First step :clean the soft light pollutants (dust, the floe content)
Use the air ball blowing off the surface of the lens skimmer, if cannot blow off the pollutant, continue to the second. Note: do not use compressed air of the factory, because it contained a lot of water and oil, oil and water In the membrane of the surface can form the absorption of harmful film.
( the lens with a mirror only need the first step)
Second step :gently clean light pollutants (dust, fingerprint)
Wet the swab or tampon with Sprinkled pure cotton, gently scrub the surface, attention to avoid the hard scrub. Across the surface as quickly as possible, beneficial to the liquid evaporated, not to leave stripe.
