## Description

Material Introduction? Gallium arsenide (GaAs) is a compound of the elements gallium and arsenic. It is a III/V semiconductor, and is used in the manufacture of devices such as microwave frequency integrated circuits, monolithic microwave integrated circuits, infrared light-emitting diodes, laser diodes, solar cells, and optical windows. 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.
