Mirror is an important component in laser processing optical path system, which would reflect light in accordance with the predetermined route and direction. Coated silicon substrates are commonly used as mirrors for CO2 lasers. Its advantages are good durability, thermal stability and relatively low cost. The total reflectors are used as rear reflectors and fold mirrors and externally as beam benders. Silicon mirrors tend to be used by lower power CO2 lasers as flat fold mirrors, and in clean conditions where back spatter and dust will not cause catastrophic failure of the mirrors. Typically a Silicon mirror has 1/10th of the laser damage resistance of a copper based mirror.
