Installation
The 10Spec accessory has been aligned and tested in the PIKE Technologies facility on the make of your
FTIR spectrometer 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
alignment screws located within the 10Spec assembly for fine-tuning once the accessory is installed in
the spectrometer.
Accessory Installation
1. Set your FTIR spectrometer to collect data at 4 cm
-1
spectral resolution (including the FTIR J-stop).
2. The 10Spec accessory fits into the sample compartment of the FTIR spectrometer. Your 10Spec is
provided with the appropriate sample compartment baseplate for the model FTIR instrument you
specified. Before inserting the accessory in the sample compartment, ensure that your
spectrometer is aligned. If the instrument is not aligned, maximize the interferogram signal (the IR
energy throughput) of your FTIR spectrometer. This should be performed by following the
manufacturer’s instructions.
3. Fasten the accessory directly into the FTIR sample compartment or onto the FTIR sample
compartment baseplate. In order to locate the accessory in the correct position, simply place the
entire accessory into the FTIR sample compartment with the 10Spec label facing the front and line
up the baseplate provided with the holes/pins in your model FTIR spectrometer.
4. Tighten the mounting screws to firmly position the accessory baseplate onto the FTIR sample
compartment baseplate.
Accessory Alignment
The 10Spec accessory may not require any alignment when installed - see page 5 for minimum energy
throughput values. However, should you choose to fine-tune the accessory, follow these steps:
1.
Place the 10Spec into the sample compartment. Using the large mask (2 inch), place the gold mirror
over the mask opening (sample position).
2.
Remove the front panel of the 10Spec by removing thumb screws.
3.
Display the live interferogram of the FTIR spectrometer and adjust the output (detector) side tilt
mirror. The location of this mirror is shown in Figure 2 (page 4). Turn the individual screws clockwise
