Our copper mirrors are made from OFHC copper, an electrolytically refined metal. This is particularly pure due to its production process and has an oxygen content of less than 0.001 per cent. A copper mirror is therefore more ductile and has a higher conductivity. Copper mirrors, which are available from Pleiger Laseroptik in flat, spherical, parabolic, toric or cylindrical versions as required, guarantee optimum performance in all areas of application. At Pleiger, we manufacture copper mirrors with dielectric or metallic coatings in-house with the highest quality standards exactly according to the specifications of our customers.
Copper mirrors are generally used where particularly high laser power can lead to extremely high heating of the substrates. After all, 0.5 to 2 per cent of the power of a laser is absorbed during operation. In this context, copper is particularly suitable for such extreme conditions due to its excellent thermal conductivity with corresponding heat dissipation and also offers further advantages over other materials in terms of mechanical stability.
Welding with the laser is mainly carried out without the addition of filler materials. Laser welding is up to eight times faster than conventional welding processes. The low energy input into the workpiece to be processed through precise and power-dense concentration on the focal spot leads to barely measurable thermal distortion. In this context, the process is equally suitable for environments with thermo-sensitive materials such as plastics or glass.
