Fitting an Attenuator to the Spectrometer
If your Spotlight 400 system is supplied with an InGaAs detector, you will be provided with
an Attenuator kit (part number L1160560) containing 1%T, 4%T, 6%T, 14%T and 32%T
attenuators. The attenuators attach magnetically to the external beam window of the
spectrometer.
Use of the 32%T attenuator is recommended if an overload error message is displayed when
using a large aperture. This attenuator should be kept in place during data acquisition.
