The variable in-line attenuator was developed for applications and setups where too much light is a problem. The attenuator is typically coupled 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 light source leg of a setup, where large core diameter fibers or bundles are used.
