CO2 optics for resonators, deflection units, and beam bending.

Copper Mirrors - CO2 and IR mirrors

OFHC (Oxygen-Free High Conductivity) Copper, also referred to as Oxygen-free Copper (OFC) is an electrolytically refined Copper. It’s of high purity  with a level of oxygen as low as 0.001 % or below. It is more ductile and has a higher thermal and electrical conductivity.

Our mirrors are coated for maximum reflectivity. PLEIGER’s manufacturing capability covers high power optics for CO2-lasers and optical instruments.

Copper mirrors are available plano, spherical, aspherical, toroidal, and with internal cooling.
