Direct-attach Fiber-optic Attenuator

Direct-attach Fiber-optic Attenuator
 
||| |||

When light intensity has to be reduced, the direct-attached attenuator is a great choice with your AvaLight series light sources. The attenuator helps in situations where detector saturation is an issue. It is attached to the light source and has a SMA connector to couple to other measurement devices and your spectrometer.

The attenuation can be set from 0-100%, which can be fixed with a set screws. It is supplied with a UV/VIS/NIR collimating lens.

The ATT-DA series attenuators come in two versions: the ATT-DA is meant to be used with the AvaLight-DHc, the AvaLight-XE and AvaLight-LED. The ATT-DA-HAL-Mini is meant to be used with an AvaLight-HAL -Mini light source.
