Installation
The MIRacle accessory has been aligned and tested in the PIKE Technologies facility to ensure that it
performs to specifications. However, some variation in optical alignment can occur from spectrometer
to spectrometer. To allow for this difference, there are four alignment screws provided on the MIRacle
base optics assembly for fine-tuning once the accessory is installed in the spectrometer. The following is
the procedure for accessory installation and final alignment.
1. The MIRacle accessory fits into the sample compartment of the FTIR spectrometer. Your MIRacle is
set to an appropriate configuration to fit the sample compartment of the FTIR instrument you
specified. Before inserting the accessory in the sample compartment, ensure that your spectrometer
is aligned. If the instrument is not aligned, follow the manufacturer’s instructions for maximizing the
interferogram signal (the IR energy throughput) of your FTIR spectrometer. In order to locate the
accessory in the correct position, simply place the entire accessory into the FTIR sample
compartment with the PIKE MIRacle label facing the front and line up the base plate provided with
the holes/pins in your FTIR Spectrometer.
2. Fasten the accessory onto the FTIR sample compartment base plate using the captive screw(s)
located on the MIRacle base plate (some accessories may have two mounting screws or a mounting
screw/pin combination, depending on spectrometer configuration).
3. Tighten the captive mounting screw (with flat head screwdriver or by hand) to firmly position the
accessory base onto the FTIR sample compartment base plate. The MIRacle accessory is now ready
for optical alignment.
