Used for CO2 laser system a semipermeable reflector/output coupling mirrors
A semipermeable reflector is usually as laser output coupling lens or beam attenuator to use, output mirrors is mainly used for laser resonant cavity laser power and output mode guaranteed with carbon dioxide laser. In industrial output mirrors, part of the total energy of the laser resonator, will return to another part of the energy output resonator used to cut, welding, and heat treatment.

The laser output couplers often need wedge with small basal to eliminate multiple reflection interference internal components. If you need a particular wedge value in order, please quote.
