Co2 laser focus lens .
1 Co2 laser focus lens used in laser cutting , laser welding and laser engraving machines ,
2. It used to focus the laser beam into one point , and make the energy of the laser point reach a very large value ,rapidly combust of workpiece to make cutting and engraving available ,
3.On the market focus lens is distinguished by two structure : meniscus and plano convex ,Becuse meniscus lens has a better at focusing , so with the same price we recommend customer to used crescent-shaped lens .
Lens information detail :
Diameter | Focal Length | Edge Thickness | Structure | Material | |||
mm | inch | mm | inch | mm | inch | ||
20 | 0.78 | 100 | 4 | 2 | 0.08 | plano-convex,Meniscus | ZnSe(USA) |
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 right and high quality focus lens ?
1 Take a measure for the diameter of lens .
2 Secondly measure the focus length
3 How to identify USA import material lens and Chinese material lens ?
Color is different
After you finish these 3 steps , you can choice a suitable focus lens for your laser engraving and cutting machine
After you choice a suitable lens , You need to learn a better way to clean lens
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.
