OFHC copper mirror

OFHC copper mirrors for maximum laser power

OFHC copper mirror

Our copper mirrors are made from OFHC copper (OFHC = Oxygen-Free High Conductivity), an electrolytically refined metal. This is particularly pure due to its production process and has an oxygen content of less than 0.001 %. Optical mirrors made from this material are typically diamond-machined and are flat, spherical or toric in shape. You can therefore choose from a wide range of product variants. Of course, we also offer high-quality optical mirrors as customised individual products. However, large and small series production is also part of our wide range of services. Copper mirrors are used as total reflectors for laser cutting and offer maximum reflection with excellent cooling options with active or passive water cooling.

Pleiger Laseroptik supplies mirrors and focussing lenses for laser cutting and welding systems that meet the highest standards of precision and material quality required in laser welding for joining or cutting metals and plastics. Mirror optics that are cooled directly are generally used for higher laser powers. Metal mirrors made of copper are used in welding and cutting optics, for example, as these require materials that can withstand extreme thermal loads. Concave or convex mirror surfaces focus, widen or direct the laser beam as required. Finally, a focussing mirror concentrates the laser beam and directs it directly onto the workpiece to be processed.

Copper mirrors, which are available from Pleiger Laseroptik in flat, spherical, parabolic, toroidal 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 mirror Applications

Copper mirrors are generally used where particularly high laser powers can lead to extremely high heating of the substrates. After all, up to 2% of the power of a laser is absorbed during operation with uncoated copper mirrors and < 0.2% with coated ones. 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 transfer into the workpiece to be processed through precise and power-dense focussing 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.

Copper mirrors for laser systems

Copper mirrors are primarily used in areas where high laser power and extreme thermal loads occur. Their excellent thermal conductivity enables effective heat dissipation, which increases the stability and service life of the laser system.
