Rear Mirrors for CO₂ Laser Systems
Optimize laser performance with long radius rear resonator mirrors that deliver high reflectivity, as well as some transmission for power monitoring.
These rear mirrors are fabricated from GaAs, Ge, or ZnSe to provide the very high levels of reflectance (99.0%-99.7%) required for efficient laser operation, together with a small amount of transmission to enable power monitoring.
Concave CO2 Laser Rear Mirrors Selection
Select from standard products on GaAs, Ge, or ZnSe, or specify custom mirrors from Si, Cu, or Mo substrates when total reflectivity is required.
