Laser power attenuators LA

Laser power attenuators allow for gradual adjustment of the laser radiation's energy or power. 

APPLICATIONS:

  • Scientific research

  • Industrial laser systems

  • Micromachining laser systems

DESCRIPTION:

Laser power attenuators are designed to smoothly adjust the energy or power of laser radiation.
The attenuator is made up of a phase plate and a thin-film polarizer positioned at a Brewster angle. The polarizer allows P-polarization to pass while reflecting S-polarization. The phase plate rotates the polarization plane, and transmission is controlled by adjusting the phase plate.

These attenuators are compatible with a wide range of laser radiation sources, including:

1064nm, 1030nm, 532nm, 515nm, 355nm, 343nm, 266nm, and 257nm.
