Description

Détails

Optical components of the Advanced Laser Power Attenuators are made for high LIDT applications and provide stable and reliable performance even when using them with high power lasers in industrial applications.
The secondary laser beam from the laser power attenuator unit is rejected out through the output window to an external beam dump (optional) in order to avoid any thermal effects or stress in the housing of the Laser Power Attenuator device. An exit laser beam has a 2.25 mm beam offset.
