Why need silicone washers for lens and mirror?
When laser machine working, temperature of laser head and mirror mount will be hot. If the mirror and lens touch mirror mount and laser head directly, the coating film of them will be damaged and the service life will be shortened. The silicone washer can isolate them to protect lens and mirror.
