Aligning the MCT Detector
The detector must be aligned when the microscope is first installed in your system.
After that, it needs realignment only when it has been removed from the system
and renewed, or when you suspect that it is not receiving the maximum signal. You
will need the cross-head screwdriver that was supplied with the microscope.
WARNING
Laser radiation will become accessible if the MCT detector is
removed.
If the MCT detector is to be removed from a Spectrum BX or
Model 1600, first block off the laser radiation by selecting the
FT-IR’s internal beam path.
1. Switch off the microscope and disconnect the mains supply.
2. Remove the two screws that secure the microscope top cover; one is on the
right at the rear, and the other at the front underneath the MCT detector
cover. Lift off the cover vertically.
The red MCT dewar and the metal frame and springs that support it become
visible (Figure 43).
