Symptom
Possible Cause
Solution
Signal is weak without a
sample in beam path,
continued…
Stage bumped the condenser or
objective
Center and focus the condenser and focus the
objective.
See
“Preparing the optics” in the
“Preparing the Microscope” chapter.
When you are finished, run the Noise Test in
transmission and reflection modes.
See
“Testing microscope performance” later in
this chapter if you need help.
If the image cannot be brought into sharp
focus, performance has dropped off, or the
Noise Test fails, contact technical support.
Parameter settings are
incorrect.
Make sure Sample Compartment, Detector,
Aperture, Velocity and Gain parameters are
set correctly.
Find
“parameters” in OMNIC
Help system Index and go to “Bench
features.”
Signal is weak without a
sample in beam path,
continued…
Infrared energy from
spectrometer is low.
Set Sample Compartment to Main and verify
that infrared energy level in spectrometer
sample compartment is normal (check signal
intensity on Bench tab in Experiment Setup
dialog box).
Find
“parameters” in OMNIC
Help system Index and go to “Bench
features,” if you need help.
Microscope is not in correct
mode.
Select mode by setting Sample Compartment
parameter.
Find
“Sample compartment
parameter” in OMNIC Help system Index
and go to “Specifying the sample location.”
Compensation ring on infrared
objective or condenser (or
both) is set incorrectly.
Adjust compensation ring and refocus the
objective and condenser.
See
“Refractive
index compensation” in the “More about the
Hardware” chapter.
