NOTE:
If your Spotlight 200 system is supplied with a Frontier or Spectrum 400
FT-IR/FT-NIR dual-range spectrometer and this has been setup to work in the
near infrared, you may find that there is a red tint to the image when viewed in
the visible range. To remove this, fit a 1%T attenuator to the external beam
window of the spectrometer. See
Fitting an Attenuator to the Spectrometer
page 48 for details.
This attenuator should be removed during data acquisition.
6.
If you need fine focus, use the
Adjust Up
or
Adjust Down
buttons on the
accessory toolbar to move the stage a small distance along the z-axis.
You can select the size of the Z-Axis Adjustment in the Setup Microscope Basic tab.
7.
If you are examining the sample in transmittance mode, you may need to adjust the
position of the lower cassegrain so that the field of view is evenly illuminated (this is
especially useful if the sample is in a compression cell or held between windows of high
refractive index):
Adjust the

control in the Setup Microscope Advanced tab by clicking the up
or down
buttons.
OR
Click
