The attenuator is essential for situations where detector saturation is a concern. The direct-attached attenuator is mounted directly onto the light source and features an SMA connector, allowing easy coupling to other measurement devices and your spectrometer. The attenuation can be adjusted from 0% to 100% and securely fixed using set screws. It is supplied with a UV/VIS/NIR collimating lens, ensuring optimal light collimation for accurate measurements.
