Inline Fiber Optic Attenuator

The variable in-line attenuator was developed for applications and setups where too much light is a problem. The attenuator is typically couples between 2 SMA terminated fibers and consists of 2 UV/VIS/NIR collimating lenses and a rotating iris.The attenuation can be set from 0-100% and fixed with a set screw. The in-line attenuator is most efficiently mounted in the illumination leg of a setup, where large core diameter fibers or bundles are used.
