Plane Mirrors

Plane Mirrors (passive reflector or tilted mirror)

Plane mirrors within a CO2 laser system (beam source) are often known as internal resonator mirrors or passive reflectors. Outside this source, these mirrors are used to direct the laser light towards the machine’s working area (beam guidance).

Generally, these mirrors are manufactured from silicon or copper whereby, copper with its higher heat conductivity, possesses the greatest form stability particularly when combined with water cooling. Both silicon and copper mirrors are nearly always finished with a highly reflective coating.

The direct water-cooling of the LT Ultra mirror units has undergone continuous improvement and optimization resulting in a working solution that suits all applications.
