If you have an MCT detector for the MIR range, you will be supplied with an Attenuator kit
(part number L1160560) containing 1%T, 4%T, 6%T, 14%T and 32%T attenuators. The
attenuators attach to the window magnetically. You will require the ferritic window surround
(part number C1201453) to attach the attenuators to the new windows.
Before you change to the MIR MCT detector in Spectrum software, fit one of the attenuators
supplied to the window to the right of the sample compartment to prevent the detector from
overloading. If you have an open beam, we recommend a 14%T attenuator.
