Advanced Laser Power Attenuators

Laserand offers motorized laser power attenuators for laser power control. Laser Power Attenuators could be produced for use in the UV, visible, and NIR spectral ranges from 250 nm to 2000 nm. These devices feature a large clear aperture dedicated for considerable beam application.


This device is combined with a unique mechanical design which ensures repeatability and high stability of performance.

Description

Details

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.
