Laser to Fiber Couplers with Attenuator Shutters

Key Features

  • High power handling
  • High resolution
  • Polarization insensitive attenuator/ shutter
  • Wide attenuation range
  • Manual and electrically controlled versions
  • Different connector receptacles


OZ Optics offers source to fiber couplers with built in attenuators or shutters. These couplers provide a precise method to control the intensity of light through a fiber. They are available in both receptacle style and pigtail style. Source couplers are available with both manual and electrically controlled attenuators.

In the manual version, the beam from the laser is partially blocked by a precision blocking screw. Adjusting the screw controls how much light reaches the fiber. In the electrically controlled version, a stepper motor controls the amount of attenuation. It includes a homing sensor to calibrate the attenuator against.
