VARIABLE ATTENUATOR

Built to Solve. Designed to Perform.

The Variable Attenuator developed by MSRC is an inline, motorized optical attenuation system designed to provide continuous, high-dynamic-range laser power control for 1064 nm laser applications. The assembly integrates beam expansion optics, logarithmically coated neutral density filters, and a brushless motor drive to achieve precise and repeatable attenuation while maintaining beam quality.

Product Highlights

  • Motorized variable attenuator for continuous optical density adjustment.
  • Continuous OD variation from 0 to 8.0 OD at 1064nm.
  • Brushless motor drive for precise and repeatable attenuation control.
  • Integrated beam-expanding optics for wide range of input intensity and fluence levels.
  • Inline optical configuration for easy system integration.

LogarithMIC Coated filters

The attenuator contains four motorized Inconel neutral density filters, allowing continuous and precise adjustment of optical density from 0 to 8.0 OD at 1064 nm.

Integrated beam expansion and collimation

Upstream and downstream beam-expanding optics reduce power density on the filters, enabling operation over a wide range of input intensity and fluence levels.
