Product Description
Znse 10600nm 10.6um CO2 Focal Laser Lens
Diameter: 12mm 18mm 19.05mm 20mm 25mm
FL: 1", 1.5" 2" 2.5" 3" 4"
Comparation between them three
Znse: Suitable for all power CO2 laser engraving machine.
CVD znse: It has better transmission effect than normaly znse lens and a little bit longer life than the normal one.
GaAs: The coating is better than znse lens
Those kind of lens are plato-convex
Thickness: 3mm
It is consuming material so that the working life of it depends on the output of your laser. Normally a normal znse lens can be used on 40W CO2 laser engraver for 8-10 month. The higher the laser output is, the shorter the working life is.
Dia.20mm Focus Lens For CO2 Laser/Lazer Engraving Cutting Machine
Focus lens, spare parts of laser engraver, laser engraving machine, laser cutting machine
CO2 laser focusing lens is widely used in laser processing for example, cutting, drilling, sculpture, engraving and laser system

working life:
1. K9 mirror can work for CO2 laser less than 40w. normally, the working life will take 2000-4000 hours
2. SI and MO mirror can work for CO2 laser more than 40w, normally, the working life will take 2000-5000 hours. for example, if you use it on 60w laser, it can work for 5000 hours, if you use it on
150w laser, it may work for 2000 hours.
3. znse and GAAS laser: 2000-5000 hours. the higher the output is, the shorter the working life it is.
4. CVD znse: 3000-6000 hours. but it gets better permeability than normal znse and gaas.
clean:
step 1: please use 100% alcohol to clean the mirror/lens. there is a protective painting on the MO surface, please use 100% alcohol to clean it before you use it.
step 2: do not use a normal towel to clean the alcohol. we recommend soft cloth and let the alcohol volatilized naturally.
step 3: avoid any scratch and skip. if the mirror/lens get any scratch, we do recommend you change it asap. otherwise the mirror/lens may be cracked and hurt people.
warranty:
1. mirror/lens are consuming material, we can replace the item only if they are not used.
2. since they are consuming material, and if you want to return it, please return the package to us within 1 day you receive the package.
Please tell us the focal length you require via ebay message. Or we will mail one to you by random.:-)
Withstand high power density; the film is solid, resistant to wipe. And because of the double-side film, the filterability of the light (the wavelength is 10.6µm) can reach 99%.
