When light intensity must 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, meant to be used with the AvaLight-DHc, the AvaLight-XE, and the ATT-DA-HAL-Mini, meant to be used with an AvaLight-HAL-S-Mini light source.
