ZnSe Material Description:
ZnSe is used for optical windows, lenses, mirrors, prisms and optical blanks, plates, disks, sheets, slabs particularly for infrared applications
Zinc Selenide (ZnSe) - transparent in wide spectral range from yellow (visible) to far IR. ZnSe material is a chemically inert, non-hygroscopic and highly pure product that is very effective in many optical applications due to its extremely low bulk losses, high resistance to thermal shock and stability in virtually all environments, easily machined. To obtain superior transmittance, ZnSe crystals are grown by Chemical Vapor Deposition process. Zinc Selenide is polycrystalline material, demonstrates superior CO2 laser transmittance and is employed in the transmission optical components used in CO2 laser processing.

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.
